Question

find the zeros of the polynomial 2 x square - 3 x minus 2​

Answer 1

p(x)= 2x²-3x-2

To Find : The zeroes of the above polynomial.

Solution :

2x²-3x-2 = 0

2x²-4x+x-2 = 0

2x(x-2)+1(x-2) = 0

(x-2)(2x+1) = 0

Here, x = 2 and x = -½.

What is a polynomial?

A polynomial is an algebraic expression having the degree of it's variables as a whole number.

For example - 2, x , x+4, 4x³ etc.

The classification of polynomials can be done in two ways :

• On the basis of degree :

★ Linear Polynomial - The polynomial having the degree = 1

★ Quadratic Polynomial - The polynomial having the degree = 2

★ Cubic Polynomial - The polynomial having the degree = 3

• On the basis of terms :

★Monomial : The polynomial having a single term only.

★ Binomial : The polynomial having two terms.

★ Trinomial : The polynomial having 3 terms.
