Question

Check whether x+1is a factor of 4x3+3x2-4x-3

Answer 1

Answer:

0

Step-by-step explanation:

$x+1=0\\x=-1\\putting x=-1\\in above equation\\we get\\4((-1)^{3})+3((-1)^{2})-4(-1)-3\\-4 +3 +4-3\\=0$

Answer 2

Step-by-step explanation:

x + 1 = 0

x = -1

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

p(-1) = 4(-1)^3 + 3(-1)^2 - 4(-1) -3

= -4 + 3 + 4 -3 = 0
