Identify a, b, c: Identify a, b, and c in the quadratic expression g2+6g+8.The quadratic expression is in the standard form ag2+bg+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 are looking for two numbers that multiply to 8 and add up to 6. The numbers 2 and 4 meet these criteria because 2×4=8 and 2+4=6.
Write factored form: Write the factored form using the two numbers found in Step 2.The factored form of the quadratic expression is (g+2)(g+4), because when multiplied out, it gives the original expression g2+6g+8.
