Question

What are the factors of 5x2 − x − 6?

(5x − 6)(x + 1)

(5x − 1)(x + 6)

(5x − 3)(x + 2)

(5x − 2)(x + 3)

Answer 1

For this you have to split the equation 5X^2 - X -6, to do that you have to split the coefficient of the X term (in this case the coefficient = -1) the two number when multiplied give you a value of (5* -6 = -30). So you can write -X as (-6X + 5X).

Answer 2

A?

Answer 3

Now you can rewrite the equation as follows
5X^2+5X-6X-6
which can be further simplified as 5X*(X+1) - 6X*(X+1)

Answer 4

So ya you are correct!
