Applicare la formula: $a+\frac{b}{c}$$=\frac{b+ac}{c}$, dove $a=-\sqrt{4x-3}$, $b=1$, $c=5x^2+1$, $a+b/c=\frac{1}{5x^2+1}-\sqrt{4x-3}$ e $b/c=\frac{1}{5x^2+1}$

Applicare la formula: $-\left(a+b\right)$$=-a-b$, dove $a=5x^2$, $b=1$, $-1.0=-1$ e $a+b=5x^2+1$

Applicare la formula: $x\left(a+b\right)$$=xa+xb$, dove $a=-5x^2$, $b=-1$, $x=\sqrt{4x-3}$ e $a+b=-5x^2-1$
