Front

What is the formula to calculate the height of an object in free fall?

Back

h = -16t² + vt + h₀, where v is the initial velocity and h₀ is the initial height.

Front

How do you find the time when an object reaches a certain height using a quadratic equation?

Back

Set the height equation equal to the desired height and solve for t.

Front

What does factoring a quadratic expression involve?

Back

Finding two binomials that multiply to give the original quadratic expression.

Front

What is the vertex form of a quadratic equation?

Back

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

Front

How do you simplify the expression -8(5b + 2) - 7(b - 5)?

Back

Distribute and combine like terms to get -47b + 19.
