Ok

Let get them to one side

5n^2-9n^2

- anonymous

ok

- anonymous

5n^2-9n^2 =0

- anonymous

n^2(5-9)=0

- anonymous

-4n^2=0

- anonymous

so n is 0

- anonymous

ok could it be n=0 or 9/5?

- anonymous

no.
5(9/5)^2\[\neq\]9(9/5)^2

do you use the same formula for this one ? Given the equation: (2x - 87)(x + 5) = 0
Find all solutions for x

- anonymous

When there are in factor(parenthesis) it is actually much easier.
you just look at each factor individually. First one is (2x-87)
2x=87;x=87/2 . the second factor (x+5) is just -5

I get this one! It is easy for real!
