Simplify: (4a + 2b)(a - b)

a) 4a^2 - 6ab - 2b^2
b) 4a^2 - 2ab - 2b^2
c) 4a^2 - 8ab - 2b^2
d) 4a^2 + 2ab - 2b^2

∠acb = 8°

step-by-step explanation:

∠xba lies on the circle and is half the measure of the intercepted arc ax

hence

measure of arc ax = 2 × 42° = 84°

∠acb is outside the circle and is

∠acb = (arcab - arcax ), hence

∠acb = 0.5 (100 - 84) = 0.5 × 16° = 8°
