Take 45 to the right hand side, divide by 5 and get the square root of it.

YAY thxs

- anonymous

this is the working they showed me 5x^2 - 45 = 0
1. divide by 5
5(x^2 - 9) = 0
2. It's easy to factor the x^ - 9 polynomial!
x^2- 9 = (x+3)(x-3)
you can check this with FOIL if you want, but I promise it's right!
So, the answer is:
5(x+3)(x-3)=0
x = 3, -3

but after you take the square root of both sides, doesn't that give you plus/minus root(9)?
