-2x^2+5x=0
-x(x+5)=0
-x=0
x=0 answer.
x=5=0
x=-5 answer.
15c^2-12c=48
15c^2-12c-48=0
3(5c^2-4c-16)=0
Using the quadratic equation:we have:
x=(4+-sqrt[-4^2-4*5*-16])/2*5
x=(4+-sqrt[16+320])/10
x=(4+-sqrt336/10
x=(4+-18.33)/10
x=(4+18.33)/10
x=22.33/10
x=2.233 answer.
(x=4-18.33)/10
x=-14.33/10
x=-1.433 answer.
