Mathematics MA2019 (2019) Grade: 8 Accelerated | 5. Use the structure of an expression to identify ways to rewrite it. [Algebra I with Probability, 5]
Example: See x4 - y4 as (x2)2 - (y2)2, thus recognizing it as a difference of squares that can be factored as (x2 - y2)(x2 + y2). Unpacked Content
| Mathematics MA2019 (2019) Grade: 8 Accelerated | 11. Select an appropriate method to solve a quadratic equation in one variable.
a. Use the method of completing the square to transform any quadratic equation in x into an equation of the form (x - p)2 = q that has the same solutions. Explain how the quadratic formula is derived from this form.
b. Solve quadratic equations by inspection (such as x2 = 49), taking square roots, completing the square, the quadratic formula, and factoring, as appropriate to the initial form of the equation, and recognize that some solutions may not be real. [Algebra I with Probability, 9] Unpacked Content
