Question

5x^2-5x-30=0 (Split the middle term)

Answer 1

In these kinds of questions
\[Ax^2 + Bx + C = 0\]
You have to find 2 numbers that would MULTIPLY to give AC
And that will add or subtract to give B
In this case
\[5x^2-5x-30=0\]
5x can be split as 15x - 10x
Because
15 * 10 give us AC = 150
And 15-10 give us 5 that is B
Getting me?
