What is the domain of the absolute value function?

Back

The domain of the absolute value function is (-∞, ∞).

Front

How do you solve a quadratic equation by factoring?

Back

To solve a quadratic equation by factoring, express the equation in the form (x - p)(x - q) = 0, where p and q are the roots.

What does the absolute value equation |2x - 3| = 4x - 1 represent?

Back

It represents two cases: 2x - 3 = 4x - 1 and -(2x - 3) = 4x - 1.

Front

What is the standard form of a complex number?

Back

The standard form of a complex number is a + bi, where a is the real part and b is the imaginary part.

What are the steps to factor a quadratic expression?

Back

1. Identify a, b, and c in ax^2 + bx + c. 2. Find two numbers that multiply to ac and add to b. 3. Rewrite the expression and factor by grouping.

Front

What is the significance of the discriminant in a quadratic equation?

Back

The discriminant (b^2 - 4ac) determines the nature of the roots: if positive, two real roots; if zero, one real root; if negative, two complex roots.

How do you find the vertex of a quadratic function?

Back

The vertex can be found using the formula (-b/2a, f(-b/2a)).

Front

What is the relationship between the roots and coefficients of a polynomial?

Back

For a quadratic ax^2 + bx + c, the sum of the roots is -b/a and the product is c/a.
