Front

Find the product: (3x + 2)(2x + 4)

Back

6x² + 16x + 8

Front

Solve the system of equations by substitution: What is the solution?

Back

No solution

Front

Identify the 'c' value in the quadratic equation: y = 16x² - 8x - 24

Back

-24

Front

What should you do first in solving this equation: x² + 6x - 13 = 3?

Back

Make it equal 0 by subtracting 3 on each side

Front

Determine the values of a, b, and c for the quadratic equation: 4x² - 8x = 3

Back

a = 4, b = -8, c = -3

Front

What is the standard form of a quadratic equation?

Back

y = ax² + bx + c

Front

What does the 'a' value in a quadratic equation determine?

Back

The direction of the parabola (upward if a > 0, downward if a < 0).

Front

How do you find the vertex of a parabola given by the equation y = ax² + bx + c?

Back

Use the formula x = -b/(2a) to find the x-coordinate of the vertex.

Front

What is the quadratic formula?

Back

x = (-b ± √(b² - 4ac)) / (2a)

Front

What does the discriminant (b² - 4ac) tell you about the roots of a quadratic equation?

Back

If > 0: two real roots, = 0: one real root, < 0: no real roots.
