Identify Coefficients: Identify the coefficients of the quadratic expression, which are a=1 (coefficient of z2), b=13 (coefficient of z), and c=22 (constant term).
Find Multiplying Numbers: Look for two numbers that multiply to c (22) and add up to b (13). After some trial and error, we find that 11 and 2 do the job because 11×2=22 and 11+2=13.
Write Factored Form: Write the factored form using the two numbers found. The quadratic expression z2+13z+22 can be factored as (z+11)(z+2).
