Factor the trinomial completely.12×2 – 42x – 24

Solve the equation.x2 – x = 20

Graph: y = -2x – 3

Graph: y = -2x + 5

Simplify: (8x + 3)2

Solve: 3(y + 8) = 7(y – 3) + 1

Evaluate the expression: -5x + 3y – 4zfor x = -2, y = 3, z = -4.

Simplify: 24 – [7 – (2 – 8)] + (3 – 5)3

Perform the indicated operations and simplify. – 7 + 5

Simplify: (7x + 4)2
