OpenStudy (kc_kennylau):

For example, here is what i would do to a^2=4-5a: a^2=5a-4 a^2-5a+4=0 (a-1)(a-4)=0 a-1=0 or a-4=0 a=1 or a=4

OpenStudy (kc_kennylau):

can you do it to your equation now?

OpenStudy (mertsj):

You need to get it equal to 0 by adding 10t to both sides and then subtract 1 from both sides. Do that first.
