Problems on radicals in algebra

Problems on Radicals in Algebra:

1. Multiply √6. √12

Solution√6. √12 = √ (6*12)

= √ (72)

= √ (18*4)

= √18. √4

= 2√18

2. Multiply 2√12. 3√4

Solution 2√12. 3√4 = (2*3) √ (3*4) √4

= 6*2*2√3

2√12. 3√4 = 24√3

3.Divide 3√12/ 3√4

Solution:3√12/ 3√4 = √12/√4

= 2(√3)/2

= √3

3√12/ 3√4= √3

Area of a rectangle

Area of a rectangle formula:


Rectangle defined as four sided plane surface area whose opposite sides are equal point and parallel point and every angle is a right angle. multiplied and height to calculate the area of a rectangle. Properties of the .opposite sides of rectangle are equal to opposite angles of rectangle are equal is the properties of a parallelogram.

Formula for area of rectangle formula:

Area of rectangle = length x breadth

To find the area of a plane figure region , we have to draw a figure and write an appropriate formula.using the given values, and calculate the required area.

how to solve math problems


how to solve math problems ?

Mathematics represents the counting, measurement and telling shapes of objects. Math using different types of solution to solve problem.

Different methods of solve math problems are:

  • Probability
  • Arithmetic
  • Number theory
  • Algebra
  • Trigonometry
  • Foundations
  • Geometry

( math answers to all problems ) Basically we remember 4 questions.

They are

  • How do I know?
  • What do I want?
  • How can I do?
  • Does it make sense?

polynomial function


Let us learn about polynomial function

In the linear algebra, there are different types of polynomials like monomial, minimal polynomial, complex polynomial. A complex polynomial can be is either zero or it can be written as the sum of one or more non-zero terms but the number of term are to be finite.To get the polynomial equations the complex polynomials or the minimal polynomials are been combined by using the commutative, associative, and distributive laws, by combining like terms.

The degree of a constant term is 0.

A function ƒ of the one argument is known as polynomial function if it satisfies

f(x) = anxn + an-1xn-1 + ... + a2x2 + a1x + a0

For all arguments of x, where n is a non-negative integer and a0, a1, a2, ..., an are constant coefficients.

The minimal polynomial is not always the same as characteristic polynomial. Consider a matrix 4In, which has characteristic polynomial (x – 4)n. It’s the minimal polynomial is x − 4, since 4In − 4In = 0, so they are different for n > 2. The minimal polynomial always divides characteristic polynomial.

elimination method


Solving simultaneous equation by elimination method is otherwise called as addition method to solve any given simultaneous equations.

In this method, we eliminate one of the unknowns.

Step 1 :- Multiply the given equations by suitable numbers so as to make the coefficients of one of the unknowns, numerically equal

Step 2 :- Add the new equations, if the numerically equal coefficients are opposite in sign, otherwise, subtract them.

Step 3 :- The resulting equation is linear in one unknown. Solve it to obtain the value of one of the unknowns.

Step 4 :- Substitute the value of this unknown in any of the given equations. Solve it to vet the value of the other unknown.

An equation that has only one variable degree is 1 called a simple equation. A linear equation in one variable is the form of Ax + B=0. And A linear equation (linear equation calculator)involves two variables is the form of Ax +By +c =0. Here x and y are variables and A, B, C are constants. When two variables in two linear equations are satisfied by the same pair of values of the variables, the equations are called simultaneous linear equations.

Definition of a Matrix:

A rectangular array of entries is called a Matrix. The entries may be real, complex or functions.

The entries are also called as the elements of the matrix.

The rectangular array of entries are enclosed in an ordinary bracket or in square bracket. Matrices are denoted by capital letters.

Example:

(i)

Note that the entries in a given matrix need not be distinct.

(ii)

The entries in this matrix are function of x.

A matrix having m rows and n columns is called as matrix of order mxn. Such a matrix has mn elements.

In general, an mxn matrix is in the form

Where aij represents the element in ith column.

The above matrix may be denoted as A = [aij]mxn.
