Answer 1

Explicación paso a paso:

1).

$\frac{ {x}^{2} - 4 }{x + 2} = \frac{(x + 2)(x - 2)}{x + 2} = x - 2$

2)

$\frac{ {a}^{2} - 4 {b}^{2} }{a + 2b} = \frac{(a + 2b)(a - 2b)}{a + 2b} = a - 2b$

3)

$\frac{4 {x}^{2} - 9 {m}^{2} {n}^{4} }{2x + 3m {n}^{2} } = \frac{(2x + 3m {n}^{2})(2x - 3m {n}^{2}) }{2x + 3m {n}^{2}} = 2x - 3m {n}^{2}$

4)

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

5)

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