Rewrite each expression using the distributive property and simplify, if possible. 15x-10x

검증된 단계별 안내

Identify the common factor in the terms 15x and -10x. Both terms have the variable \( x \) and numerical coefficients 15 and 10.

Use the distributive property, which states \( a(b + c) = ab + ac \), in reverse to factor out the common term \( x \) from both terms.

Write the expression as \( x(15 - 10) \), factoring out \( x \) from both terms.

Simplify the expression inside the parentheses by subtracting 10 from 15, resulting in \( x(5) \).

Rewrite the expression as \( 5x \), which is the simplified form after applying the distributive property.

주요 개념

질문에 올바르게 답하기 위해 반드시 이해해야 하는 핵심 개념들은 다음과 같습니다.

Distributive Property

The distributive property states that multiplying a sum or difference by a number is the same as multiplying each term inside the parentheses by that number separately. For example, a(b + c) = ab + ac. This property helps in rewriting expressions by factoring or expanding.

Combining Like Terms

Combining like terms involves adding or subtracting terms that have the same variable raised to the same power. For example, 15x and -10x are like terms because both contain x. Simplifying expressions often requires combining these terms to write a simpler equivalent expression.

Simplification of Algebraic Expressions

Simplification means rewriting an expression in its simplest form by performing operations like addition, subtraction, multiplication, or division. After applying the distributive property and combining like terms, the expression should be simplified to a single term or a simpler expression.
