Question

1. Find the value of the polynomial 4x2 – 5x +3, when
(i) x = 0
(ii)x=-1
​

Answer 1

Step-by-step explanation:

At x = 0

4(0)-5(0)+3

3

At x = -1

4(-1)² -5(-1)+3

4+5+3

12

Answer 2

Step-by-step explanation:

• (i). ×=0
• 4×2-5(0)+3
• 8-0+3
• 8+3
• 11

• (ii). ×=-1
• x=-1
• 4×2-5(-1)+3
• 8+5+3
• 8+8
• 16

answer = (i) = 11

(ii) = 16
