Identify Variables: Identify a, b, and c in the quadratic expression m2+11m+18. The quadratic expression is in the form of ax2+bx+c, where a=1, b=11, and c=18.
Find Multiplying Numbers: Find two numbers that multiply to c (18) and add up to b (11).We need to find two numbers that multiply together to give 18 and when added together give 11. The numbers 2 and 9 satisfy these conditions because 2×9=18 and 2+9=11.
Write Factored Form: Write the factored form using the two numbers found in Step 2.The factored form of the quadratic expression is (m+2)(m+9), because these two binomials multiply out to the original quadratic expression m2+11m+18.
