Question

find cubic polynial having -3,2 and-5 as its zeroes

Answer 1

Hi ,

Let p( x ) is a required cubic

polynomial.

It is given that - 3 , 2 and -5 are the

Zeroes of p ( x )

Therefore ,

P( x ) = ( x + 3 ) ( x - 2 ) ( x + 5 )

= ( x² - 2x + 3x - 6 ) ( x + 5 )

= ( x² + x - 6 ) ( x + 5 )

= x³ + 5x² + x² + 5x - 6x - 30

= x³ + 5x² - x - 30

I hope this helps you.
