Which Expression Is Not A Polynomial Math
However 2y2 7x 1 x is not a polynomial as it contains division by a variable.
Which expression is not a polynomial math. Negative exponents are a form of division by a variable to make the negative exponent positive you have to divide. Polynomials cannot contain division by a variable. Polynomials have no variables in denominators or exponents no roots or absolute values of variables and all variables have whole number exponents. F x 1 x 2x 2 5 as you can see 1 x can be written as x 1 which is not satisfying definition non negative integer power.
F x ax 2 bx c where a b and c are real numbers. Polynomials cannot contain negative exponents. You cannot have 2y 2 7x 4. Math secondary school the expression which is not a polynomial is the expression which is not a polynomial is 3x x 11 x 3x 7 11x xy 5 7 x x.
The expression x2 3 x 1 x 2 3 x 1 is not a polynomial as we have a non integer exponent of the variable in the second term. Note carefully that the constraint of integer exponents applies only to exponents of the variable s and not of any constants.
