Question

How do you simplify `(3x-1)(2x+6)`?

Answer 1

`6x^2 + 16 - 6`

Explanation:

So here we just use multiplication in brackets which means that you take the first term in the first parenthesis and multipliy it by the two other terms in the other parenthesis, then take the second term in the first parenthesis and multiply it buy both terms in the second parenthesis. It's a bit hard to describe in words so let's use maths!

This picture is the principle we're using so let's just apply that.

`(3x-1)(2x+6)= 3x*2x + 3x *6-1*2x-1*6=6x^2 + 18x-2x-6 = 6x²+16x-6`
