simplify (z^2-11zy+28y^2)/(z-7y)

simplify

\frac{z ^{2} - 11 zy + 28 y ^{2}}{z - 7 y}

z - 4 y

Solution steps

\frac{z ^{2} - 11 zy + 28 y ^{2}}{z - 7 y}

Factor

z^{2} - 11 zy + 28 y^{2} : (z - 4 y) (z - 7 y)

= \frac{( z - 4 y ) ( z - 7 y )}{z - 7 y}

Cancel the common factor:

z - 7 y

= z - 4 y

3.2 a - 1 - 4 \frac{1}{3} a + 7 - a

0. 7^{- 0.45}

\frac{( x ^{3} + 27 )}{( x + 3 )}

5 \frac{1}{16}

(2 x + 1) (3 x - 4)
