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 - 4)(x - 6).

Front

What is the significance of the discriminant in factoring quadratics?

Back

The discriminant, given by b² - 4ac, determines the nature of the roots of a quadratic equation: if positive, there are two distinct real roots; if zero, one real root; if negative, no real roots.
