Question

find the value of polynomial when x=3 in x2-4x+7​

Answer 1

Answer:

Correct option is

C

8

Given polynomial is p(x)=4x

2

−3x+7

We need to find value of polynomial at x=1.

Then put the value of x=1 in the given polynomial, we get

p(x)=4(1)

2

−3(1)+7

⇒p(x)=4×1−3×1+7

⇒p(x)=4−3+7

⇒p(x)=11−3=8

So, value of polynomial is 8.
