Sagot :
the answer would be (x+6)(x+3) because when you add the last number you will get the middle term when you multiply it you will get the last term which is 18
x^2+9x+18
x+3
x+6
x^2+3x
+6x+18
x^2+9x+18
therefore the factors of x^2+9x+18 is:
(x+3)(x+6)
x+3
x+6
x^2+3x
+6x+18
x^2+9x+18
therefore the factors of x^2+9x+18 is:
(x+3)(x+6)
