What are the solutions to the equation (x - a)(x + b) = 0?
Match each quadratic expression in factored form with it's equivalent expression in standard form. One expression in standard form has no match.
| Stavka koja se može prevući | arrow_right_alt | Odgovarajuća stavka |
|---|---|---|
(x - y)(x - y) | arrow_right_alt | y2 - x2 |
(x - 11)(x + 11) | arrow_right_alt | 121 - x2 |
No match | arrow_right_alt | x2 - 121 |
(11 + x)(11 - x) | arrow_right_alt | x2 -2xy + y2 |
(y + x)(y - x) | arrow_right_alt | x2 + 2xy - y2 |
Is (x - 3)(x + 3) equivalent to (3 - x)(3 + x)?
Show that (5 + 1)(5 - 1) is equivalent to 52 - 12
We are multiplying together two numbers in the expressions (30 - 2)(30 + 2) and 302 - 22. What is one of the two numbers we are multiplying?
