A coefficient cannot be zero because when we multiply 0 (as a coefficient) with any variable, the value of the term results in 0. [see note below] How d you form an algebraic expression to express this and identify the variable, constant and coefficient of the expression? Some examples of variables include: These variables can take on different values that depend on the situation we are in. If two algebraic expressions are equivalent, then the two expressions have the same value WebThis expression is bearing the degree of 4 which is the highest one in the whole polynomial. 4 is an algebraic expression called constant algebraic expression because 4 can be written as 4 with any variable whose power is 0 and anything raised to power 0 is 1 . Solve Now. If you're looking to improve your academic performance, try studying with a friend or group. For avoiding confusion, the coefficient that is not attached to unknown functions and their derivative is generally called the constant term rather the constant coefficient. In other words, a coefficient is the numerical factor of a term containing constant and variables. That is, a number being multiplied by a variable, such as x. In particular, in a linear differential equation with constant coefficient, the constant term is generally not supposed to be a constant function. For example: Remember that we need to be careful about zero denominators when we find a variable in the denominator of a term. A coefficient is a numerical value that is multiplied with a variable.
