21y5 - 28y4 + 14y3
————————————————————
7y
This is division by a monomial
There are three terms in the top, so begin by drawing
three lines:
—————— —————— ——————
Now put the signs of the terms between the lines:
—————— - —————— + ——————
Now copy the denominator 7y under every line:
—————— - —————— + ——————
7y 7y 7y
Write the terms above the lines
21y5 28y4 14y3
—————— - —————— + ——————
7y 7y 7y
Give 1 exponents to the y's in the bottoms
21y5 28y4 14y3
—————— - —————— + ———————
7y1 7y1 7y1
Cancel the 7's into the numerators:
3 4 2
21y5 28y4 14y3
—————— - —————— + ———————
7y1 7y1 7y1
1 1 1
3y5 4y4 2y3
—————— - —————— + —————
1y1 1y1 1y1
Subtract exponents to divide the y's
3y4 4y3 2y2
—————— - —————— + —————
1 1 1
3y4 - 4y3 + 2y2
