Factor & Solve Quadratics

Front

What is the standard form of a quadratic equation?

Back

The standard form of a quadratic equation is ax^2 + bx + c = 0, 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 are the roots of a quadratic equation?

Back

The roots of a quadratic equation are the values of x that make the equation equal to zero.

What is the factored form of the quadratic x^2 - 5x + 6?

Back

The factored form of the quadratic x^2 - 5x + 6 is (x - 2)(x - 3).

Front

How do you determine the number of real roots of a quadratic equation?

Back

The number of real roots can be determined using the discriminant (b^2 - 4ac). If the discriminant is positive, there are two real roots; if it is zero, there is one real root; if negative, there are no real roots.

What is the vertex of a parabola represented by a quadratic equation?

Back

The vertex of a parabola is the highest or lowest point on the graph, depending on the direction of the parabola (opening upwards or downwards). It can be found using the formula (-b/2a, f(-b/2a)).

Front

What is the axis of symmetry in a quadratic function?

Back

The axis of symmetry is a vertical line that divides the parabola into two mirror-image halves, given by the equation x = -b/2a.

Front

What is the quadratic formula?

Back

The quadratic formula is x = (-b ± √(b^2 - 4ac)) / (2a), used to find the roots of a quadratic equation.
