General Quadratic Word Problems (page 2 of 3) The height h is 4/3 the width, so h = (4/3) w. Then the area is A = hw = [ (4/3) w ] [ w] = (4/3) w2 = 192. I need to solve this "area" equation for the value of the width, and then back-solve to find the value of the height.
Lesson Using quadratic equations to solve word problems
Problem 2. Working together and separately to complete a job. You get the quadratic equation. Apply the quadratic formula (see the lesson ) to solve this equation. The equation has two roots: and . The second root does not fit the given conditions: if Bill covers the roof in two days, then Andrew has 2-5=-3 days, which has no sense. So, the potentially correct solution is : Bill covers the roof in 15 days.
