%281%2F5%29x=sqrt%282x-25%29 /^2 both sides of equation
%281%2F25%29x%5E2=2x-25 multiply both sides by 25
X%5E2-50x%2B625=0
x+=+%28-%28-50%29+%2B-+sqrt%28+%28-50%29%5E2-4%2A1%2A625+%29%29%2F%282%2A1%29+
x+=+%2850+%2B+sqrt%28+0%29%29%2F2+
x=25
In this type of equations you always have to check answer
Put x=25 in equation
1%2F5%2A25=sqrt%282%2A25-25%29
5=sqrt%2825%29
5=5 correct
Answer 25
