What is an exponent?

Simplify: $3x^2 + 2x - x^2 + 5x$

Factor: $x^2 - 9$

What is the distributive property in algebra?

Solve for $x$: $x + 3 < 10$

Simplify: $(4x^2 + 3x - 2) - (2x^2 - x + 5)$

Solve the system: $x + y = 10$ and $x - y = 2$

What is FOIL used for?

Solve for $x$: $x/4 = 5$

What does it mean to "factor" an expression?

Multiply: $(2x - 1)(x + 5)$

Simplify: $7y - 2y + 4$

Solve: $x^2 = 16$

What is a quadratic equation?

Solve for $x$: $\dfrac{x - 3}{2} = 4$

Simplify: $x^8/x^3$

What are "like terms"?

Solve for $x$: $2x - 5 \geq 7$

Evaluate when $x = 3$: $2x + 5$
