Question

Q.6) For the polynomial
p(x) = x3 – 2x² + x +4, find p(1) and p(-2)
4, 11
4,-14
5, 14
-4, 14​

Answer 1

Answer:

4, -14

Step-by-step explanation:

p(1) = 1 - 2*1 + 1 + 4

= 1-2+1+4

=4

p(-2) = -8 - 2*4 -2 + 4

= -8 - 8 - 2 + 4

=-14

I hope it will help you....

Answer 2

Step-by-step explanation:

p(x)=x³-2x²+x+4

p(1)=(1)³-2(1)²+1+4

=1-2+5=-1+5=4

p(-2)=(-2)³-2(-2)²+(-2)+4

=-8-2(4)-2+4

=-8-8+2

=-16+2

=-14

option is (B) (4,-14)
