Solve 4m² - 100 = 0

Back

m = 5, -5

Front

Simplify 9∛32

Back

18∛4

Front

Solve for x: 5(x - 3)² + 1 = 81

Back

x = -1, 7

Front

Solve 2x² + 16x + 14 = 0

Back

x = -7, -1

Front

Use the quadratic formula to find the solutions for y = -x² - 5x + 12

Back

No Real Solution

Front

What is the quadratic formula?

Back

x = (-b ± √(b² - 4ac)) / (2a)

Front

What does it mean if the discriminant (b² - 4ac) is negative?

Back

There are no real solutions.

Front

What is the vertex form of a quadratic equation?

Back

y = a(x - h)² + k, where (h, k) is the vertex.

Front

How do you find the vertex of a parabola given in standard form?

Back

Use h = -b/(2a) to find x-coordinate, then substitute to find y.

Front

What is the axis of symmetry in a quadratic function?

Back

x = -b/(2a)
