Identify Common Factor: First, look for a common factor in all terms. 2w2, 18w, and 36 all have a common factor of 2. Factor out the 2: 2(w2+9w+18).
Factor Quadratic Inside: Now, factor the quadratic inside the parentheses.We need two numbers that multiply to 18 (the constant term) and add up to 9 (the coefficient of w).The numbers 3 and 6 work: 3×6=18 and 3+6=9.
Write Factored Form: Write the factored form using the numbers 3 and 6.2(w+3)(w+6) is the factored form of the quadratic.
Check Factored Form: Check the factored form by expanding it to see if we get the original expression. 2(w+3)(w+6)=2(w2+6w+3w+18)=2w2+12w+6w+36=2w2+18w+36.It matches the original expression, so the factoring is correct.
