Identify a, b, c: Identify a, b, and c in the quadratic expression t2+13t+22.The quadratic expression is in the form at2+bt+c, where a=1, b=13, and b0.
Find two numbers: Find two numbers that multiply to c (22) and add up to b (13).We need to find two numbers that multiply to 22 and add up to 13. The numbers 2 and 11 satisfy these conditions because:2×11=22 (product is c)220 (sum is b)
Write factored form: Write the factored form using the two numbers found in Step 2.The factored form of the quadratic expression is (t+2)(t+11), because:(t+2)(t+11)=t2+2t+11t+22=t2+13t+22
