# HOLT ALGEBRA 1 LESSON 9-9 PROBLEM SOLVING THE QUADRATIC FORMULA AND THE DISCRIMINANT

Ruby Parsons 2 years ago Views: Vocabulary Words and Definitions for Algebra Name: The manager of a park enclosed an area for small dogs to play. Substitute 6 for a, 5 for b, and —4 for c. The height of the trapezoid is twice as long as the shorter base and the longer base is twice as long as the height. Integers and Real Numbers 1. Systems of Linear Equations 8. Some cannot be solved by any of these methods, but you can always use the Quadratic Formula to solve any quadratic equation. There are two real solutions b2 — 4ac is zero. Warm Up Simplify each expression. Use the quadratic formula. Use the elimination method when the coefficients of one of the variables are the same or opposite. An object is shot up from 4 feet off the ground with an initial velocity of 48 feet per second. What is the length of the longer base?
