Question

100 POINTS! I REALLY NEED TO GET THIS CORRECT! Factor the quadratic trinomial.

Answer 1

The factors of the equation $x^2-3x-18$ are $(x-6)(x+3)$

Step-by-step explanation:

We need to factor the quadratic trinomial. $x^2-3x-18$

We will do factorization by braking the middle term such that adding those number we get middle term (-3x) and multiplying those numbers we get (-18x^2)

Solving:

$x^2-3x-18\\=x^2-6x+3x-18\\=x(x-6)+3(x-6)\\=(x-6)(x+3)$

So, the factors of the equation $x^2-3x-18$ are $(x-6)(x+3)$
