Answer 2

Step-by-step explanation:

Question 1. Find the value of the polynomial 5x – 4x2 + 3 at

(i) x = 0 (ii) x = –1 (iii) x = 2

Question 1. Find the value of the polynomial 5x – 4x2 + 3 at

(i) x = 0 (ii) x = –1 (iii) x = 2

Solution: (i)x = 0

5x – 4x2 + 3

Plug x = 0 we get

=>5(0) – 4(0)2 + 3

=>0 -0 + 3

=> 3

(ii) x = –1

Plug x = - 1 we get

=>5x – 4x2 + 3

=>5(-1) – 4(-1)2 + 3

=> -5 – 4 +3

=>-6

(iii) x = 2

Plug x = 2 we get

=>5(2) – 4(2)2 + 3

=>10 – 16 + 3

=> -3
