Step 4: Put factors into the open boxes. 4x2 12x -x - 3 Step 5: Factor the terms in each row and in each column Step 6: The sum of the What Property Is Used In Solving Quadratic Equations The degree of the trinomial is the highest degree in the expression. Thinking of distribution, 13x comes from multiplying the outer terms:(2x + 3)(x + 5) = 2x2 + 10x + 3x + 15...multiplying the inner terms:(2x + 3)(x + 5) = 2x2

We want -2x in the middle, not 2x.
