Identify a, b, c: Identify a, b, and c in the quadratic expression t2+5t+6.The quadratic expression is in the form at2+bt+c, where a=1, b=5, and b0.
Find two numbers: Find two numbers that multiply to c (6) and add up to b (5).We need to find two numbers that multiply to 6 and add up to 5. The numbers 2 and 3 fit this requirement because 2×3=6 and 2+3=5.
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+3), because when we expand this, we get t2+2t+3t+6, which simplifies to t2+5t+6.
