Full solution

Q. Factor.\newlinez2+12z+11z^2 + 12z + 11
  1. Identify Coefficients: Identify the coefficients for z2z^2, zz, and the constant term.\newlineThe quadratic expression is in the form z2+bz+cz^2 + bz + c, where bb is the coefficient of zz, and cc is the constant term.\newlineFor z2+12z+11z^2 + 12z + 11, b=12b = 12 and c=11c = 11.
  2. Find Multiplying Numbers: Find two numbers that multiply to c(11)c (11) and add up to b(12)b (12). We need to find two numbers mm and nn such that m×n=11m \times n = 11 and m+n=12m + n = 12. The numbers 11 and 1111 satisfy these conditions because 1×11=111 \times 11 = 11 and 1+11=121 + 11 = 12.
  3. Write Factored Form: Write the factored form using the numbers found in the previous step.\newlineThe factored form of the quadratic expression is (z+m)(z+n)(z + m)(z + n).\newlineSubstitute m=1m = 1 and n=11n = 11 into the factored form to get (z+1)(z+11)(z + 1)(z + 11).
