Question

The polynomial who's factors are( x+2) (x-2)

Answer 1

Answer:

${x}^{2} - 4$

Answer 2

Answer :

x² - 4

Explanation :

A polynomial is defined as the product of factors.

In this question, we have to find the quadratic polynomial whose factors are ( x + 2 ) ( x - 2 ). So, we have to multiply these factors to find the required polynomial.

So the polynomial is given by,

= ( x + 2 ) ( x - 2 )

= x ( x - 2 ) + 2 ( x - 2 )

= x² - 2x + 2x - 4

= x² - 4

So the required polynomial is x² - 4.

This is of the form ax² + bx + c where b is equal to 0 .
