Terms: 3x^2, x, and 7 Coefficients: 3 and 1 Constants: 7
Practice makes perfect
An algebraic expression is a combination of numbers, variables, and mathematical operations. Terms are separated by + or - signs. With this information in mind, let's identify the terms in the given expression.
3x^2 + x + 7We can see that the expression has three terms, 3x^2, x, and 7. Next, we will identify the coefficients and constants. A coefficient is a number that is multiplied by a variable or variables. Variables on their own, without a number next to them, actually have a coefficient of 1. A constant is a number with no variable factors.
3x^2+x+7
⇕
3x^2+ 1x+ 7
The expression has two coefficients, which are 3 and 1, and a constant, which is 7. Let's organize this information in a table.
