Question

. Find P(0), P(-1) for P(x)=2x-2x² + 4x-5.
plz with explanation​

Answer 1

Step-by-step explanation:

P(X) = 5-4X+2X² => 2X²-4X+5

(1) P(0) = 2 × (0)² - 4 × 0 +5 = 0-0+5 = 5

(2) P(3) = 2 × (3)² - 4 × 3 +5 = 2 × 9 -12 +5 = 18-12+5 = 11

(3) P(-2) = 2 × (-2)² - 4 × -2 + 5 = 2 × 4 +8 +5 = 8+8+5 = 21.

HENCE,

P(0) = 5 , P(3) = 11 AND P(-2) = 21.

Answer 2

Step-by-step explanation:

P(0)=2×0-2×(0)²+4×0-5

=0-0+0-5

=-5

P(1)=2×(-1)-2×(-1)²+4×(-1)-5

= -2-2+(-4)-5

= -4-5

= -9
