Find all values of c such that c/(c - 5) = 4/(c - 1). If you find more than one solution, then list the solutions you find separated by commas.
+37157 x/(x - 5) = 4/(x- 1) cross multiply , then solve the resulting quadratic
x( x-1) = 4 (x-5)
x^2 -5x +20 = 0 Use quadratic formula to solve for x (I changed it from 'c' to avoid confusion with the quad formula)
\(x = {-b \pm \sqrt{b^2-4ac} \over 2a}\)
