Factoring Quadratics

Front

What is the standard form of a quadratic equation?

Back

The standard form of a quadratic equation is ax² + bx + c, where a, b, and c are constants and a ≠ 0.

What does it mean to factor a quadratic expression?

Back

Factoring a quadratic expression means rewriting it as a product of its linear factors.

Front

What is the greatest common factor (GCF)?

Back

The greatest common factor is the largest factor that divides two or more numbers or expressions.

Front

How do you factor the expression x² - 10x + 24?

Back

To factor x² - 10x + 24, find two numbers that multiply to 24 and add to -10. The factors are (x - 6)(x - 4).

Front

What is the difference of squares?

Back

The difference of squares is a special factoring pattern that states a² - b² = (a + b)(a - b).
