Question

Factor form of x^2-x-30

Answer 1

(x - 6)(x + 5)

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)

Answer 2

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

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)`
