Algebra 1

3. A letter or symbol (like x or y) that represents an unknown value or one that can change
5. A number or expression that divides evenly into another number or expression (factors of x² - 4 are (x+2) and (x-2))
9. An expression with variables and coefficients using only addition, subtraction, multiplication, and positive integer exponents (like 3x² + 2x + 1)
11. A mathematical statement showing the relationship between expressions using <, >, ≤, or ≥
14. A mathematical statement showing that two expressions are equal (like 2x + 3 = 11)
15. An equation or expression where the highest power of the variable is 2 (like ax² + bx + c)

1. The number that multiplies a variable (in 5x, 5 is the coefficient)
2. A polynomial with exactly two terms (like x + 3 or 2x - 5)
4. A mathematical phrase that can contain numbers, variables, and operations (like 2x + 3)
6. A symbol (√) used to indicate a root of a number or expressionTerm A number, variable, or product of numbers and variables (in 3x² + 2x + 1, each part is a term)
7. A number, variable, or product of numbers and variables (in 3x² + 2x + 1, each part is a term)
8. A number that shows how many times a base is multiplied by itself (in x², 2 is the exponent)
10. Terms that have the same variables raised to the same powers (3x² and -2x² are like terms)
12. An equation or expression where the highest power of the variable is 1 (like mx + b)
13. A rule that assigns exactly one output to each input value
