Q. Solve for h.h2−11h+18=0Write each solution as an integer, proper fraction, or improper fraction in simplest form. If there are multiple solutions, separate them with commas.h = ____
Identify quadratic equation: Identify the quadratic equation to be solved.The given quadratic equation is h2−11h+18=0. We need to find two numbers that multiply to 18 and add up to −11.
Find multiplying numbers: Find two numbers that multiply to 18 and add up to −11. The numbers −2 and −9 multiply to 18 (−2×−9=18) and add up to −11 (−2+−9=−11).
Rewrite using numbers: Rewrite the quadratic equation by splitting the middle term using the numbers found in Step 2.h2−2h−9h+18=0
Factor by grouping: Factor by grouping.Group the terms to factor by common terms:(h2−2h)−(9h−18)=0Factor out an h from the first group and a −9 from the second group:h(h−2)−9(h−2)=0
Factor out common factor: Factor out the common binomial factor.(h−2)(h−9)=0
Solve for h: Solve for h by setting each factor equal to zero.h−2=0 or h−9=0
Final solutions: Solve each equation for h.For h−2=0, add 2 to both sides to get h=2.For h−9=0, add 9 to both sides to get h=9.
