(two *x + three)/(x + six) - (x^ two + three *x - eighteen)/(x + six)^ two = zero
(2 multiply by x plus 3) divide by (x plus 6) minus (x squared plus 3 multiply by x minus 18) divide by (x plus 6) squared equally 0
(two multiply by x plus three) divide by (x plus six) minus (x to the power of two plus three multiply by x minus eighteen) divide by (x plus six) to the power of two equally zero
(2*x + 3)/(x + 6) - (x2 + 3*x - 18)/(x + 6)2 = 0
2*x + 3/x + 6 - x2 + 3*x - 18/x + 62 = 0
(2*x + 3)/(x + 6) - (x² + 3*x - 18)/(x + 6)² = 0
(2*x + 3)/(x + 6) - (x to the power of 2 + 3*x - 18)/(x + 6) to the power of 2 = 0
