Question

ayudaaa k mañana tengo examen y ando más perdida​

Answer 1

Explicación paso a paso:

a)

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

B)

$\frac{5(x + 3)}{( x+ 3{)}^{2} } = \frac{5}{(x + 3)}$

C)

$\frac{3(x + 1)}{3( {x}^{2} - 1) } = \frac{1}{ {x}^{} - 1}$

D)

$\frac{(x + 1)(x + 1)}{5x(x + 1)} = \frac{x + 1}{5x}$

E)

$\frac{x(5x - 6)}{x( {x}^{2} - 12x + 18)} = \frac{5x - 6}{ {x}^{2} - 12x + 18}$

F)

$\frac{3 {x}^{3} + 6 {x}^{2} + 3x }{6 {x}^{3} + 6 {x}^{2} } = \frac{3x( {x}^{2} + 2x + 1 )}{3x(2 {x}^{2} + 2x)} = \frac{(x + 1 {)}^{2} }{2x(x + 1)}$

$\frac{x + 1}{2x}$
