Question

Ada yg bisa gak tolong dong

Answer 1

X/(x+1) - (x-2)/(3x+3)
= (x(3x+3) - (x+1)(x-2))/(x+1)(3x+3)
= (3x^2 + 3x - (x^2 - x - 2))/(3x^2 + 6x + 3)
= (3x^2 + 3x - x^2 + x + 2) / (3x^2 + 6x + 3)
= (2x^2 + 4x + 2) / (3x^2 + 6x + 3)
= 2/3 (x^2 + 2x + 1)/(x^2 + 3x + 1)

Answer 2

X/x+1 - x-2/3x+3=x(3x+3)/(x+1)(3x+3) - (x-1)(x+1)/(x+1)(3x+3)
                       =(3x²+3x)/3x²+6x+3 - (x²-1)/3x²+6x+3
                       =2x²+3x+1/3x²+6x+3
