AI overview
A coefficient is a number or expression that multiplies a variable or term in a mathematical equation—for example, in the expression 2x² - x + 3, the numbers 2, -1, and 3 are coefficients. Coefficients matter because they tell you the scale or weight of each part of an equation, which is essential for solving problems and understanding how changes in variables affect the overall result.
