Question

Find the value of the polynomial 5x - 4x2 + 3 at
(1) x=0
(i) x=-1
(iii) x=2
​

Answer 1

Answer:

here is your answer :

(i) x=0

5x - 4x^2 + 3

5 (0) - 4 (0)^2 +3

0-0+3=3

(ii) x= -1

5 (-1) - 4 (-1)^2 + 3

-5 -4 +3 = -9 + 3 = -6

(iii) x=2

5(2) - 4 (2)^2 + 3

10 - 16 + 3 = 13 - 16 = -3

Answer 2

Answer:

$\huge \bold\fcolorbox{blue}{pink}{AnsWer:}$

Let P(x) = 5x−4x^2+3

(i) When x = 0

P(0) = 5(0)-4(0)^2+3

= 3

(ii) When x = -1

P(x) = 5x−4x^2+3

P(−1) = 5(−1)−4(−1)^2+3

= −5–4+3

= −6

(iii) When x = 2

P(x) = 5x−4x^2+3

P(2) = 5(2)−4(2)^2+3

= 10–16+3

= −3
