Question

Factor form of x^2-x-30

Answer 1

Answer: $(x+5)(x-6)$

Step-by-step explanation:

To solve the exercise you must keep on mind the following:

- You must find two numbers whose sum is -1 and whose product is -30.

- These numbers would be 5 and -6.

Therefore, you can factor the quadratic equation given in the problem above $x^2-x-30$, as you can see below:

$x^2-x-30\\(x+5)(x-6)$

Answer 2

Answer:

(x - 6)(x + 5)

Step-by-step explanation:

You know that in order to get x^2 there has to be two x's so you get:

(x ...)(x...)

Then you also know that two numbers have to multiply together and equal 30 but also have a sume of -1. So you get:

(x - 6)(x + 5)
