An equation is formed of two equal expressions. Janes should multiply both sides of the equation by (y²-1).
<h3>What is an equation?</h3>An equation is formed when two equal expressions are equated together with the help of an equal sign '='.
The equation that is given is an equation with a mixed fraction, therefore, the denominator with the highest power should be multiplied on both sides of the equation. The equation that is given to us
As we can see in the equation that there are 2 denominators, which are,
- y²-1
- y+1
In the two of the expressions that are stated above the expression (y²-1) is of a higher power.
Hence, Janes should multiply both sides of the equation by (y²-1).
