_________ combines numbers, variables, and mathematical operators to

represent a value or set of values.

• linear equation

• algebraic expression

• unit expression

9x is an example of what type of expression

• Cubic expression
• Self expression

• algebraic expression

Expand

2(2x+4)

simplify

2(2x + 4) − 2(3 x −5)

simplify

x + 2 y + 5x - y

• 7x + 3y
• 5x + 2y
• 8x + 4y
• 6x - y

solve
2x²−5x−3 = 0

x²−16=0

• -4 and 4

• -4 and 2

• 4 and -8

find the solution to 4x²−12x+9=0

2x + 5 > 3x − 2

3(2x−1) ≤ 5x+4
