Question

Find the value of the polynomial P(x)=8x^2-3x+7 at x=-1 and x=2
Find a zero of the polynomial P(x)= 3x +2.​

Answer 1

Step-by-step explanation:

P(x) = 8x^2-3x+7

x=-1

P(-1)=8(-1)^2-3(-1)+7

=8 + 3 +7

=18

x=2

P(2)=8(2)^2-3×2+7

=32 - 6 + 7

=33

zero of polynomial,

P(x) = 3x+2 = 0

3x= -2

x= -2/3
