Question

Pls help me to get answer

Answer 1

Answer:

Step-by-step explanation:

x+2=0

Therefore

x=-2 using factor theorem

p(x)= 4x^4 + 2(x)^3-3x^2 + 5x +5a

Substitute value of x in p(x)

Therefore

4*(-2)*(-2)*(-2)*(-2)+2*(-2)*(-2)*(-2)-3(-2)*(-2)+5*(-2) + 5a=0 as -2 is one of the zeroes of p(x)

64-16-12-10 + 5a=0

26+5a=0

5a=-26

a=-26/5

Hope it helps
