Question

whether X + 2 is a factor of x square - 4 x minus 12​

Answer 1

Answer:

yes x+2 is a factor of $x^{2}$-4x-12

Step-by-step explanation:

p(x)=$x^{2}$-4x-12

given x+2 as factor

from this x=-2

substitute the value of x in the equation

p(-2)=$(-2)^{2}$-4(-2)-12

      =4+8-12

       =0

so x+2 is a factor $x^{2}$-4x-12

Answer 2

Answer:

Yes x+2 is a factor

Step-by-step explanation:

x²-4x-12=(x-6) (x+2(
