Expand the brackets in the following expression
(5y-3)^2
------------------
Factorise the following expressions
x^2 - x - 12 (2)
9y^2-25
I've several questions like this if someone could let me know what to do with this one then maybe I could get an idea of what to do with the rest. Thanks!
------------------
solve the equation.
9/(x=7)= 4/(x-3)
