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

a) 3x²-x/2a+1 - x²-2x/2a+1

3x²-x-x+2x/2a+1

2x²+x/2a+1

b) 3/2x²+8/x

3/2x²+2x.8/2x.x

3/2x²+16x/2x²

3+16x/2x²

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

9ax+5x-11v

14x-11v
