Identify Coefficients: Identify the coefficients for z2, z, and the constant term.The quadratic expression is in the form z2+bz+c, where b is the coefficient of z, and c is the constant term.For z2+12z+11, b=12 and c=11.
Find Multiplying Numbers: Find two numbers that multiply to c(11) and add up to b(12). We need to find two numbers m and n such that m×n=11 and m+n=12. The numbers 1 and 11 satisfy these conditions because 1×11=11 and 1+11=12.
Write Factored Form: Write the factored form using the numbers found in the previous step.The factored form of the quadratic expression is (z+m)(z+n).Substitute m=1 and n=11 into the factored form to get (z+1)(z+11).
