Answer 2

Răspuns:

a. $\frac{32x^{7} - 48x^{6} }{-16x^{5} }$+$x^{2}$-3x

de aici scoti factor comun 16 $x^{5}$

$\frac{16x^{5} (2x^{2}-3x) }{-16x^{5} }$+ $x^{2}$-3x

simplifici 16 si $x^{5}$

-(2$x^{2}$-3x)+$x^{2}$-3x

-2$x^{2}$+3x+$x^{2}$-3x

simplifica 3x si -3x

-$x^{2}$

b. $\frac{18x^{5} - 27x^{4} }{-9x^{3} }$ + 2$x^{2}$+10x

factor comun 9$x^{3}$

$\frac{9x^{3} (2x^{2}-3x) }{-9x^{3} }$+2$x^{2}$+10x

simplifici 9 si -9 si $x^{3}$

-(2$x^{2}$-3x)+2$x^{2}$+10x

-2$x^{2}$+3x+2$x^{2}$+10x

simplifica -2$x^{2}$ cu +2$x^{2}$

13x
