Multiplying Rational Expressions Worksheet
By color-coding the widespread factors, it’s clear which ones to remove. Now, I can multiply across the numerators and across the denominators by putting them aspect by side. The second step is canceling, or what I like to name slashing! Once we have ‘slashed’ all the like phrases from the top and bottom, we multiply straight across, however do not multiply anything we slashed! So we’re going to slash (r – 3) over (r – 3) and (r – 3) over (r – 3). Here dividing by \(2/3\) is the same factor as multiplying by \(3/2\) (since \(2/3\) and \(3/2\) are inverses of each other).
- So we merely flip the second fraction and multiply straight throughout.
