1) In a mathematical equation, a coefficient is a constant by which a variable is multiplied. Consider the following equations: 3 x 2 + 5 x - 3 = 0. ax 3 + by 2 = z. The values 3 and 5 in the first equation are coefficients of x , a variable. In the second equation, if a and b are constants, then a is a coefficient of x 3 , and b is a coefficient of y 2 .
