You can put this solution on YOUR website!
5t%5E3-45t=0
5t%5E3=45t
Divide by 5t both sides
5t%5E3%2F5t=45t%2F5t
t%5E2=9
Take square root both sides
sqrt%28t%5E2%29=sqrt%289%29
t=3%29 or t=-3%29



6x%5E2=15x
Divide by 3x both sides
6x%5E2%2F3x=15x%2F3x
2x=5
Divide by 2 both sides
2x%2F2=5%2F2
x=5%2F2
