You can put this solution on YOUR website! (x^2 -25)/x / (x+5)/(x^2-5x)
.
invert and multiply, as with fractions ,,,a/b / c/d = (a/b) * (d/c)
.
(x^2 -25)/x * (x^2-5x) / (x+5)
.
factor and combine like terms
.
{ (x+5)(x-5)} /x * { (x)(x-5) } / (x+5)
.
(x-5)* (x-5)
.
(x-5)^2
.
check,,,let x=1,,,both original and answer = 16,,,ok
