Question

Find if(-2x-5) is a factor of the polynomial p(x)=3x⁴ +5x³-2x²-4 or not.​

Answer 1

Answer:

Step-by-step explanation:p(x)=3x^4+5x^3-2x^2-4

g(x)=-2x-5

g(x)=o

-2x-5=0

x=-5/2

p(5/2)=3(5/2)^4+5(5/2)^3-2(5/2)^2-4

         =3*625/16+5*125/8-25/2-4

         =117.1+78.1-12.5-4

         =178.7
