Step 1 of 3

Math 121 Chapter 2 Notes Lesson 2.3 – Quadratic Equations In One Variable Example 1. 2 7y + 28y 2 0 (Since this is already in proper form “ax + bx + c = 0”, all we need to do is find the common factors in 7 and 28. Common factor here is 7y, since both can be divided by 7 and y, so factor out 7y.) 7y (y + 4) = 0 (By the Zero Factor Property, we know that for this product to equal zero, then at least one of the two factors must equal 0, as well. To determine the other solution of the
