Question

efetue as frações algébricas com os devidos cálculos por favor

a)
$\frac{ {3x}^{2} - x }{2a - + 1} - \frac{ {x}^{2} - 2x }{2a + 1}$
b)
$\frac{3}{2 {x}^{2} } + \frac{8}{x}$

c)
$\frac{18}{x} - \frac{25}{3}$
d)
$\frac{9 \alpha x}{a} + \frac{5ax}{a} - \frac{11av}{a}$
​

Answer 1

Resposta:

A)

3x²-x-(x²-2x)/2a+1

3x²-x-x²+2x/2a+1

2x²-x+2x/2a+1

2x²+x/2a+1

2x²+x/2a+1

B)

3/2x2 + 2x.8/2x.x

3/2x² + 16x/2x.x

3/2x² + 16x/2x²

3+16x/2x²

C)

3.18/3x - 25/3

3.18/3x - x.25/x.3

54/3x - x.25/x.3

54/3x - 25x/3x

54-25x/3x

D)

9x+ 5ax/a - 11av/a

9x+5x - 11av/a

9x+5x- 11v

14x-11v

Bons estudos :)
