Solving Quadratic Equations by Factoring

Front

What is a quadratic equation?

Back

A quadratic equation is a polynomial equation of degree 2, typically in the form ax² + bx + c = 0, where a, b, and c are constants and a ≠ 0.

Front

What is the zero product property?

Back

The zero product property states that if the product of two factors is zero, then at least one of the factors must be zero. This is used to solve equations of the form (x - p)(x - q) = 0.

What is the standard form of a quadratic equation?

Back

The standard form of a quadratic equation is ax² + bx + c = 0.

Front

What is the significance of the coefficients a, b, and c in a quadratic equation?

Back

The coefficient 'a' determines the direction of the parabola (upward or downward), 'b' affects the position of the vertex, and 'c' is the y-intercept.
