Question

Find the value of the polynomial 5x-4x 2+3 at x=2?

Answer 1

Answer:

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

P (2)=5×2-4×2^2+3

=13-16

= -3

Answer 2

Answer:

• Given polynomial 5x−4x 2 +3
• (i) If x=0
• Then 5(0)−4(0) 2 +3=0−0+3=3
• (ii) If x=−1
• Then 5(−1)−4(−1) 2 +3=−5−4+3=−6

• (iii) If x=0
• Then 5(2)−4(2) 2 +3=10−16+3=−3
