factor 21xy+15x+35ry+25r

factor

21 x y + 15 x + 35 ry + 25 r

(5 + 7 y) (3 x + 5 r)

Solution steps

21 x y + 15 x + 35 ry + 25 r

Rewrite as

= 7 \cdot 3 x y + 5 \cdot 3 x + 35 ry + 25 r

Factor out common term

3 x

= 3 x (7 y + 5) + 35 ry + 25 r

Rewrite as

= 3 x (5 + 7 y) + 7 \cdot 5 ry + 5 \cdot 5 r

Factor out common term

5 r

= 3 x (5 + 7 y) + 5 r (7 y + 5)

Factor out common term

(5 + 7 y)

= (5 + 7 y) (3 x + 5 r)

6 x^{2} - 18 x - 24 = 36

\frac{4 x ^{- 3} y ^{4}}{8 x ^{2} ( y ^{- 3} ) ^{2}}

(x^{4})^{\frac{3}{2}}

(x - 5)^{2}

- 5 x^{- 2}
