Question

Factor 6x ^ 2 - 3x - 45; 3(2x - 5) * (x + 3); 3(2x - 3) * (x - 5); 3(2x + 5) * (x - 3); 3(2x + 3) * (x - 5)

Answer 1

`3(2x+5)(x-3)`

Explanation:

The given equation is:

`6x^(2)-3x-45`

It can be solved by using middle term splitting.

So,

`6x^(2)-3x-45=6x^2+15x-18x-45\\\\=3(2x+5)(x-3)`

So, the factors of
`6x^(2)-3x-45` are
`3(2x+5)(x-3)`
