What is a coefficient?
The numerical factor in a term. Example: In 4x, 4 is the coefficient.
How do you evaluate an algebraic expression?
Substitute values for the variables. Example: For x = 2 in 3x + 4, evaluate as 3(2) + 4 = 10.
How do you combine like terms?
Identify terms with the same variable and exponent. Example: 3x + 2x = 5x.
Why is it important to review mistakes in algebra?
Analyzing errors helps avoid repeating them in the future.
What is a constant?
Fixed values that do not change. Example: In 3x + 4, 4 is a constant.
What is a tip for mastering algebra?
Practice regularly to reinforce concepts.
What is a variable?
Symbols that represent unknown values. Example: In x + 2, x is the variable.
What is the difference of squares?
a^2 - b^2 = (a + b)(a - b). Example: x^2 - 9 = (x + 3)(x - 3).
What is the distributive property?
a(b + c) = ab + ac. Example: 2(x + 3) = 2x + 6.
What is an algebraic expression?
A mathematical phrase that can include numbers, variables, and operators (e.g., 3x + 5).
How can visual aids help in learning algebra?
Diagrams and charts can clarify complex ideas.
What is a common factor in factoring expressions?
The greatest common factor (GCF) that can be factored out. Example: 6x + 9 = 3(2x + 3).
What are terms in an algebraic expression?
Parts of an expression separated by plus or minus signs. Example: In 2x + 3y - 5, the terms are 2x, 3y, and -5.
