LEARNING TARGET

I can name terms, coefficients, factors, and grouped parts.

Build the idea

Addition and subtraction separate terms. A coefficient multiplies a variable; a constant has no variable. A parenthesized sum can be one factor of a larger product, so describe both the inside and the whole expression.

WORKED EXAMPLE 1

For 5x + 2y + 6, list terms, coefficients, and the constant.

Terms 5x, 2y, 6; coefficients 5, 2; constant 6

Terms are separated by addition; coefficients multiply variables.

WORKED EXAMPLE 2

In 6(x + 7), identify the outer operation, both factors, and the operation inside the grouped factor.

Outer product; factors 6 and (x + 7); inner sum

The complete sum (x + 7) is one factor multiplied by 6.

Your turn

Work in order. Start with the foundations, then build toward explanation and application.

  1. For 7x + 5y + 3, list terms, coefficients, and the constant.

  2. For 4x + 4y + 6, list terms, coefficients, and the constant.

  3. For (2x + 3) ÷ 2, name the outer operation, the dividend as a single entity, and the divisor. Identify the sum inside the parentheses.

  4. For 3x + 4y + 3, list terms, coefficients, and the constant.

  5. For (2x + 2) ÷ 5, name the outer operation, the dividend as a single entity, and the divisor. Identify the sum inside the parentheses.

  6. For 2x + 6y + 4, list terms, coefficients, and the constant.

  7. For (5x + 6) ÷ 5, name the outer operation, the dividend as a single entity, and the divisor. Identify the sum inside the parentheses.

  8. In 5(x + 3), identify the outer operation, both factors, and the operation inside the grouped factor.

  9. In 3(x + 5), identify the outer operation, both factors, and the operation inside the grouped factor.

  10. In 7(x + 6), identify the outer operation, both factors, and the operation inside the grouped factor.
