Question

Describe and correct the error. k/k+5 + 5/k+3 = -2k/k^2+8k+15 LCD = (k+3)(k+5) k(k+3)+5(k+3) = -2k k^2 + 3k + 5k + 25 = -2k k^2 + 8k + 25 = -2k k^2 + 10k + 25 = 0 (k + 5)^2 = 0 k = -5 2x-9/x-5 - x^2+4x-5/x^2-25 = 2x-9/x-5 - (x+5)(x-1)/(x-5)(x+5) = 2x-9/x-5 - x-1/x-5 = 2x-9-x-1/x-5 = x-10/x-5
