Yep its another one! If -2 = -2 (4 – 6) = (1 – 3) add 9/4 to both sides (4 – 6 + 9/4 ) = (1 – 3 + 9/4) Simplify and factorise (2 – 3/2)2 = (1 … Continue reading →

If a = b a^2 = ab a^2 – b^2 = ab – b^2 Factorise to give (a – b) (a + b) = b (a – b) Common factor on each side cancels to give a + b  = … Continue reading →
