Answer:
Given polynomial is p(x)=4x2−3x+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.
Answer:
4(-2)2-7 ( ya,here it is -2 whole square dont get confused)
4×4-7
8-7
=1
so 1 is the answer
