Complete the square for each expression. Then factor the trinomial. 22+18x Step 1 Find one-half of b, then square it to obtain Step 2 Add the resulting G from Step 1 to x2 + bx to obtain x2 + bx + Step 3 Factor the resulting expression as ( x + 4 ) 3 2. x2 - 22x Step 1 Find one-half of b, then square it to obtain () Step 2 Add the resulting (2) from Step 1 to x + bx to obtain x? + bx + () Step 3 Factor the resulting expression as (* + 5)
