(a + b)(c + d) = ac + ad + bc + bdSlide 9: 2. (a - b)(c - d) = ac - ad - bc + bdTake A Break: Take A BreakExpanding Two Brackets:: Expanding Two Brackets: Eg. ( a + 5 )(a - 6)Expanding Two Brackets:: Expanding Two Brackets: ( a + 5 )(a - 6) = a x a + a x (-6) + 5 x a + 5 x (-6)OR: OR ( a + 5 )(a - 6) = a x a + 5 x a + a x (-6) + 5 x (-6): = a 2 + ( - 6a ) + 5a + ( - 30 ) = a 2 – 6a + 5a – 30And, a2 – 6a + 5a – 30 = a2 – a – 30: And, a 2 – 6a + 5a – 30 = a 2 – a – 30 You do not have the permission to view this presentation.
