Question

(3) Check whether (x+1) is factor of 3x^3+5x^2--2x--4​

Answer 1

Answer:

Yes it is a factor

Step-by-step explanation:

x+1=0 so,x = -1

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

f(-1)= 3(-1)^3+5(-1)^2-2(-1)-4

= -3+5+2-4

= 7-7

=0

thus (x-1) is a factor of f(x)= 3x^3+5x^2-2x-4

Answer 2

Answer:

yes is a factor. thankyou hope it helps
