How To Multiply Out Of Brackets

Education : Maths

If you have to multiply out, this means removing the brackets whilst keeping the same equation. Here is how:

Multiply out: (b - 5)^2 [^ means to the power, here squared]

This should be written as:
(b-5)(b-5)

And then multiply out as normal, to get:
b^2 - 10b + 25
