Other uncategorized cookies are those that are being analyzed and have not been classified into a category as yet. In particular, in a linear differential equation with constant coefficient, the constant term is generally not supposed to be a constant function. A coefficient is a number that is multiplied by a variable. We see that our #x# term is #color(slateblue)(-2x)#, and the constant in front of it is #-2#. An algebraic expression is a combination of constants, variables and algebraic operations (+, -,,). In 3x2 + 2x, we have 2 terms. There are 3 main types of algebraic expressions which include: An algebraic expression which is having only one term is known as a monomial. No, 4 is not an algebraic expression because an expression should have at least one variable and one operation to be algebraic. A coefficient is an integer that is written along with a variable or it is multiplied by the variable. In the first term, the numerical factor is 3, and 3 Get Started.
