Textbook Problem

For Problems 41-64, simplify each complex fraction. (Objective 2) − 1 y − 2 + 5 x 3 x − 4 x y − 2 x

To determine

To Find:

The simplest form of the given complex fraction:

1y2+5x3x4xy2x

Explanation

Approach:

Rational expression, a quotient obtained by division of two polynomials in form of p(x,y)q(x,y) where p(x,y) and q(x,y) are polynomials in such a way that the variables x, y do not assume values such that q(x,y)=0.

If ab and cd are rational, then addition or subtraction of rational formed by making the denominator equal using LCD and perform the operation on the numerators as follows:

And,

Calculation:

Here, the given expression is âˆ’1yâˆ’2+5x3xâˆ’4xyâˆ’2x.

LCD of the given expression is x(yâˆ’2).
