Question

Find zeros of cubic polynomial P of x is equal to x cube + 2 x square - 3x also verify the relationship between zeros and coefficient of P of x

Answer 1

Answer:

I hope you understand the answer clearly

Answer 2

Answer:

X=X³ +2x²-3x=0

Step-by-step explanation:

X³ + 2x² + 1x² -3x=0

x²(x+2) + 1(x+2)

(X²+1)(x+2)

Now find the zeroes and made it equal i.e.

X²+1 X+2

X=-2

X²= -1

so, two zeroes are -1,-2.now find the relationship between them.

In given equation, X³ + 2X² - 3X

A=1,B=2,C=3

-b= coffe.of x. product of zeroes.

a. coffee.of X². 3+1=3/1

2+1=2/1. 2=2.

2=2

hence verify. hence verify
