#Solving quadratic equations worksheet all methods pdf

Then substitute in the values of a, b, c a, b, c.Īpproximate the answers using a calculator. Solve the equation using the Quadratic Formula. This is a quadratic equation rewrite it in standard form. Write the formula for the area of a rectangle. The height of the triangular window is 10 feet and the base is 24 feet.ģ w − 1 = 3 w − 1 = the length of the rectangle ĭoes a triangle with height 10 and base 24 have area 120? Yes. Since h is the height of a window, a value of h = −12 does not make sense. This is a quadratic equation, rewrite it in standard form.

This will give us two pairs of consecutive odd integers for our solution.įirst odd integer n = 13 First odd integer n = −15 next odd integer n + 2 next odd integer n + 2 13 + 2 − 15 + 2 15 −13 First odd integer n = 13 First odd integer n = −15 next odd integer n + 2 next odd integer n + 2 13 + 2 − 15 + 2 15 −13ġ3, 15 yes − 13, −15 yes 13, 15 yes − 13, −15 yes There are two values of n that are solutions. The product of the first odd integer and the second odd integer is 195. “The product of two consecutive odd integers is 195.”

We are looking for two consecutive odd integers. One set of even integers and one set of odd integers are shown below. This is also true when we use odd integers. The next one would be n + 2 + 2 or n + 4. If we call the first one n, then the next one is n + 2. Remember, we noticed each even integer is 2 more than the number preceding it. We have solved number applications that involved consecutive even and odd integers, by modeling the situation with linear equations. Answer the question with a complete sentence Check the answer in the problem and make sure it makes sense. Solve the equation using algebra techniques.
