### LESSON 9-9 PROBLEM SOLVING THE QUADRATIC FORMULA AND THE DISCRIMINANT ANSWERS

Take the square root of both sides. The height of the trapezoid is twice as long as the shorter base and the longer base is twice as long as the height. The ringer will not reach a height of 20 feet. What is the length of the longer base? Method 4 Solve using the Quadratic Formula.

L pg x3, skip 21, 54, add 23, 53 63 use another method. My presentations Profile Feedback Log out. Round to the nearest foot. Method 2 Solve by factoring. Substitute 1 for a, —1 for b, and —20 for c. Use the Quadratic Formula.

Method 2 Solve by factoring. Entering —b for negative values of b. Recall that quadratic equations can have two, one, or no real solutions. To use this website, you must agree to our Privacy Policyincluding cookie policy. Registration Forgot your password?

Method 4 Solve using the Quadratic Formula. A community swimming pool is in the shape of a trapezoid. L pg x3, skip 21, 54, add 23, 53 63 use another method.

There are two real solutions b2 — 4ac is zero. Write as two equations. The object will reach its maximum height of 40 feet once. Substitute 1 for a, —1 for b, lessson —20 for c.

Solving Using Different Methods. Take the square root of both sides.
