21 OVER X squared MINUS 6x is equal to 1 OVER x(x-6)(x+5).

I have to rewrite the ration expression as an equivalent rational expression with the given denominator.

• Algebra-Can't solve! -

x^2 - 6 x = x(x-6)

So, assuming that x is not equal to zero or 6, multiply both sides by
x (x-6):

21 = 1/(x+5) ----->

x = 1/21 - 5 = - 104/21
