Factorise the following: x 2 - x(a + 2b) + 2ab

x 2 - x(a + 2b) + 2ab = x 2 - xa - 2bx + 2ab = x(x - a) - 2b(x - a) = (x - a)(x - 2b). Hence, x 2 - x(a + 2b) + 2ab = (x - a)(x - 2b).

x² - x(a + 2b) + 2ab

= x² - xa - 2bx + 2ab

= x(x - a) - 2b(x - a)

= (x - a)(x - 2b).

Hence, x² - x(a + 2b) + 2ab = (x - a)(x - 2b).
