simplify (28x^9y^6-49x^7y^3-7x^2y)/(7x^2y)

simplify

\frac{28 x ^{9} y ^{6} - 49 x ^{7} y ^{3} - 7 x ^{2} y}{7 x ^{2} y}

4 x^{7} y^{5} - 7 x^{5} y^{2} - 1

Solution steps

\frac{28 x ^{9} y ^{6} - 49 x ^{7} y ^{3} - 7 x ^{2} y}{7 x ^{2} y}

Factor

28 x^{9} y^{6} - 49 x^{7} y^{3} - 7 x^{2} y : 7 x^{2} y (4 x^{7} y^{5} - 7 x^{5} y^{2} - 1)

= \frac{7 x ^{2} y ( 4 x ^{7} y ^{5} - 7 x ^{5} y ^{2} - 1 )}{7 x ^{2} y}

Cancel the common factor:

7

= \frac{x ^{2} y ( 4 x ^{7} y ^{5} - 7 x ^{5} y ^{2} - 1 )}{x ^{2} y}

Cancel the common factor:

x^{2}

= \frac{y ( 4 x ^{7} y ^{5} - 7 x ^{5} y ^{2} - 1 )}{y}

Cancel the common factor:

y

= 4 x^{7} y^{5} - 7 x^{5} y^{2} - 1
