Lesson 6.1 Addition with Unlike Denominators Essential Question How can you use models to add fractions that have different denominators? 1 Adding 12 to each side of the equation on the first line of the example is the first step in solving the equation. We did not change the solution by adding 12 to each side since both the second and third equations have the same solution. Equations that have the same solution sets are called equivalent equations.

Dec 21, 2020 · We start with the standard form of a quadratic equation and solve it for x by completing the square. ax2 + bx + c = 0, a ≠ 0. Isolate the variable terms on one side. ax2 + bx = − c. Make the coefficient of x2 equal to 1, by dividing by a. ax2 a + b ax = − c a. Simplify. x2 + b ax = − c a.
