Reducing Rational Expression

“Reducing Rational Expression” is similar with “Simplify” which means cancel out the same factors and terms. For example, the factor below has two same terms “(x-1)”, so we can cross them out to become the simple term—– – x+2/x+3.

Because the denominator can not be zero, x can’t equal to 1 or -3.

Factors are multiplied

Terms are added subtracted
