Question

please say the answer.
for this two sums​

Answer 1

Step-by-step explanation:

Given polynomial f(x)=x2

We know that a polynomial is zero polynomial when f(x)=0

∴x2=0

⇒x=0

So value of x for zero polynomial is 0

Answer 2

Step-by-step explanation:

1) 3x-2=0

x=2/3

2)x²-x-2=0

x²-(2-1)x-2=0

x²-2x+x-2=0

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

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

x+1=0 x-2=0

x=-1 x=2
