What does it mean to translate a word problem into an algebraic expression?

Translating a word problem into an algebraic expression involves converting the words into mathematical symbols and operations. For example, 'twice a number' translates to $$2n$$ .

What is the order of operations in algebra?

The order of operations is the sequence in which calculations are performed: Parentheses, Exponents, Multiplication and Division (from left to right), Addition and Subtraction (from left to right). This is often remembered by the acronym PEMDAS.

How do you identify like terms in an expression?

Like terms are terms that have the same variable raised to the same power. For example, in $$3x^2 + 5x^2 + 2x$$ , the terms $$3x^2$$ and $$5x^2$$ are like terms.

What is the distributive property?

The distributive property states that $$a(b + c) = ab + ac$$ . It allows you to multiply a single term by each term inside a parentheses.

What is a polynomial?

A polynomial is an algebraic expression that consists of one or more terms, where each term is a product of a constant and a variable raised to a non-negative integer power. For example, $$2x^2 + 3x + 5$$ is a polynomial.

What is a term in an algebraic expression?

A term is a single mathematical expression that can be a number, a variable, or a combination of both multiplied together. For example, in $$4xy + 3x - 2$$ , there are three terms: $$4xy$$ , $$3x$$ , and $$-2$$ .

What does it mean to factor an expression?

Factoring an expression means to break it down into simpler expressions that multiply together to give the original expression. For example, $$x^2 - 9$$ can be factored into $$(x - 3)(x + 3)$$ .

What is a rational expression?

A rational expression is a fraction where the numerator and/or denominator are polynomials. For example, $$\frac{2x + 3}{x - 1}$$ is a rational expression.
