Question

1. Find the value of the polynomial 4x² – 5x +3, when
1
(i) x = 0
(ii) x=-1
(iii) x=2
(iv)x=
2​

Answer 1

P(x) = 4x² - 5x + 3

• At x = 0

4 x 0² - 5 x 0 + 3 = 0 - 0 + 3

Answer :- 3

• At x = -1

4 x -1² - 5 x -1 + 3 = 4 + 5 + 3

Answer :- 12

• At x = 2

4 x 2² - 5 x 2 + 3 = 16 - 10 + 3

Answer :- 9
