Answer (1)
Answer:A rational algebraic expression is an expression of the form P/Q,where P and Q are polynomials, and Q should not be equal to zero. You can identify a rational algebraic expression if it is in the form fraction,where the numerator and denominator are polynomials, and does not have a fractional exponent and a variable in the denominator. The denominator cannot be zero because a division by 0 is undefined or meaningless. You need to pay attention to what values of the variable that will make the denominator equal to 0. These values are called excluded values. To determine the said values, you need to let the expression in the denominator be equal to 0. Then, solve the equation to determine the value/s of the variable.
