Identify a, b, c: Identify a, b, and c in the quadratic expression p2+6p+8.The quadratic expression is in the form ap2+bp+c, where a=1, b=6, and b0.
Find two numbers: Find two numbers that multiply to c (which is 8) and add up to b (which is 6).We need to find two numbers that multiply to 8 and add up to 6. The numbers 2 and 4 satisfy these conditions because:2×4=8 (product is c)80 (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 (p+2)(p+4), because:(p+2)(p+4)=p2+4p+2p+8=p2+6p+8
