Factor Quadratic Expressions (1)

Front

What is the general form of a quadratic expression?

Back

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

Front

What does it mean to factor a quadratic expression?

Back

Factoring a quadratic expression means rewriting it as a product of two binomials.

Front

What is the factored form of the quadratic expression 8x² + 31x - 4?

Back

(8x - 1)(x + 4)

Front

How do you determine the coefficients in a quadratic expression?

Back

The coefficients are the numerical factors in front of the variables: 'a' is the coefficient of x², 'b' is the coefficient of x, and 'c' is the constant term.

Front

What is the significance of the discriminant in factoring quadratics?

Back

The discriminant (b² - 4ac) determines the nature of the roots of the quadratic equation. If it's positive, there are two distinct real roots; if zero, one real root; if negative, no real roots.
