simplify (21x^2-105x)/(7x-56)

simplify

\frac{21 x ^{2} - 105 x}{7 x - 56}

\frac{3 x ( x - 5 )}{x - 8}

Solution steps

\frac{21 x ^{2} - 105 x}{7 x - 56}

Factor

21 x^{2} - 105 x : 21 x (x - 5)

= \frac{21 x ( x - 5 )}{7 x - 56}

Factor

7 x - 56 : 7 (x - 8)

= \frac{21 x ( x - 5 )}{7 ( x - 8 )}

Factor the number:

21 = 7 \cdot 3

= \frac{7 \cdot 3 x ( x - 5 )}{7 ( x - 8 )}

Cancel the common factor:

7

= \frac{3 x ( x - 5 )}{x - 8}

- 6 (- 4 d - 8.3 + 3 d)

14 \times 2
