Question

if p(x)=4x⁵-3x⁴-5x³+x²-8. Then find p(-2) ? ​

Answer 1

Answer:

-156.

Step-by-step explanation:

p(x) = 4x⁵ - 3x⁴ - 5x³ + x²- 8

p(-2)= 4×(-2)⁵ - 3(-2)⁴ -5(-2)³+(-2)²-8

= 4(-32) - 4(16) - 5(-8) + 4 - 8

= -128 - 64 + 40 + 4 - 8

= -192 + 44 - 8

= -148 - 8

= -156.

Answer 2

p(-2)=4(-2)⁵-3(-2)⁴-5(-2)³+(-2)²-8

= -128-48+40+4-8

= -140
