Factoring trinomials worksheet (solved examples) Factorise the following Quadratic trinomials by spiliting the middle terms. We know, in order to factorise the expression ax2 + bx + c, we have to find two numbers p and q, such that p + q = b and p × q = ac. Example 1: Factorise . Solution. Find two factors p and q such that p+q=-7 and pq =12 . Take p=-3 and q=-4 then 12= -3 x (-4) and -3-4=-7 . Therefore = = = = Example 2: Obtain the factors of . Solution. = = = Example 3: Find …
