(y-3)x kwadrat - 2 ( y-3) x

x kwadrat (x-5) -(5-x) + x (5-x )

Answer 1

(y - 3)x² - 2(y - 3)x = (y - 3)(x² - 2x) = x(y - 3)(x - 2)

x²(x - 5) - (5 - x) + x(5 - x) = -x²(5 - x) - (5 - x) + x(5 - x) = (5 - x)(-x² - 1 + x)

Answer 2

(y - 3)x^2 - 2(y - 3)x= (y - 3)(x^2 - 2x)

x^2(x - 5) - (5 - x) + x(5 - x)= (5 - x) (-x^2 - 1 + x)
