Question

1. Find the value of the polynomial 5x - 4x2 + 3 at
(I) X=0
(ii) x=-1
(iii) x=2


guys please answer me​

Answer 1

Answer:

x+1 = 0

x=0-1

x=-1

5x-4x²+3

5(-1) - 4(-1)² + 3

-5 -4(1) + 3

-5-4+3

-5-1

-6

so answer is x = -1

Answer 2

Answer:

Step-by-step explanation:

(i) p(0)=5(0)-4(0)²+3

p(0)=0+3

p(0)=3

(ii)p(-1)=5(-1)-4(-1)²+3

p(-1)=-5-4+3

p(-1)=-6

(iii) p(2)=5(2)-4(2)²+3

p(2)=10-16+3

p(2)=-3

hope this help:))
