Question

find integral zeroes of 2x^3+5x^2-5x-2

Answer 1

Hello Mate!

In intergral roots we will take each digit if answer come = 0

First let's take 0

p( 0 ) = 2 ( 0 ) ^ 3 + 5( 0 )^2 - 5(0) - 2
0 is not equal to - 2
x = 0 ❎

p( 1 ) = 2(1)^3 + 5(1) - 5(1) - 2
0 = 2 + 5 - 5 - 2
0 = 0

So x = 1 ✔

So integral root of 2x^3 + 5x^2 - 5x - 2 is +1

Hope it helps☺!✌
