Answer 1

1.

$\frac{25 {y}^{2} - 36 {x}^{2} }{5y + 6x} = \frac{(5y - 6x)(5y + 6x}{5y + 6x} = 5y - 6x$

2.

$\frac{64 {a}^{2} + 27 }{4a + 3} = \frac{(4a + 3)(16 {a}^{2} - 12 a + 9) }{4a + 3} = 16 {a}^{2} - 12a + 9$

3.

$\frac{81 {m}^{2} - 100 {n}^{2} }{9m - 10n} = \frac{(9 {m} - 10n) ( 9m + 10n }{9m - 10n} = 9m + 10n$

4.

$\frac{ {x}^{6} - 27 {x}^{3} }{ {x}^{2} - 3y } = \frac{ ({x}^{2} - 3 y)( {x}^{4} + 3 {x}^{2} y + 9 {y)}^{2} }{ {x}^{2} - 3y } = {x}^{4} + 3 {x}^{2} y + 9 {y}^{2}$

5.

$\frac{27 {m}^{3} - 125 {n}^{3} }{3m - 5n} = \frac{(3m - 5n)(9 {m}^{2} + 15mn + 25 {n}^{2} )}{3m - 5n} = 9 {m}^{2} + 15mn + 25 {n}^{2}$
