Tutorial Exercise Factor the trinomial. x² + 2x-8 Step 1 Since the first term of the trinomial is x2, the first term of each binomial factor will be x. For the second terms of the binomial factors, find two numbers whose sum is 2, the coefficient of the middle term, and whose product is (-8), the last term. The order does not matter, so we will assume that the first number is the larger one (in absolute value). To begin, we ignore the signs. Possible pairs of factors of 8, with the first number being the larger one, are 8 and (x-2) Submit Skip (you cannot come back) and 4 and
