Solving Quadratics by Factoring matching game
Tap an item on the left, then its partner on the right. Beat your best time. Matching games train quick recall, which is exactly what tests ask for.
The pairs (answer key)
Zero-product property ↔ If A × B = 0, then A = 0 or B = 0
(x − 6)(x + 1) = 0 ↔ x = 6 or x = −1
x2 + 14x + 49 = 0 ↔ One solution, x = −7 (a double root)
2x2 − 10x = 0 ↔ x = 0 or x = 5
x2 − 64 = 0 ↔ x = 8 or x = −8
Graph of y = x2 + 2x − 15 ↔ Crosses the x-axis at (−5, 0) and (3, 0)
A negative solution for a width ↔ Rejected, because a length cannot be negative
x2 + 3x + 1 = 0 ↔ Prime trinomial: needs a later method
