Question

Select the factors of x2 − 12x + 36.

(x − 6)(x − 6)

(x + 6)(x + 6)

(x + 3)(x + 12)

(x − 3)(x − 12)

Answer 1

Ok so it has to equal 36 when multiplied but also equals -12 when added.

Answer 2

\[=x^2-6x-6x+36\]\[=x(x-6)-6(x-6)\]\[=(x-6)(x-6)=(x-6)^2\]

Answer 3

6x6=36, 6+6=12
12x3=36, 12+3=15
-12x-3=36, -12+(-3)=-15
so its A

Answer 4
