Question

Find weather P(x) 2x3 + 3x2-1 is the factor of X + 1.​

Answer 1

Answer:

yes, x +1 is a factor of 2x³+3x²-1

Step-by-step explanation:

p(x)= 2x³+3x²-1

g(x)= x +1

x = -1

p(-1)= 2(-1)³+3(-1)²-1

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

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

p(-1)= -3+3

p(-1)= 0

as the reminder is 0 , we can say that x+1 is the factor of 2x³+3x²-1
