Question

Simplificati fractile:
a) 4x supra 6x²y
b) x-3 supra 3x-9
c) x²-4 supra x²+2x
va rog mult..

Answer 1

$a) \frac{4x}{6 {x}^{2} y}=\frac{\frac{4x}{2x} }{\frac{6{x}^{2}y}{2x}}= \frac{2}{3xy} \: (cu \: 2x)$

$b) \frac{x - 3}{3x - 9} = \frac{x - 3}{3(x - 3)} = \frac{1}{3} \: (cu \: x - 3)$

$c) \frac{ {x}^{2} - 4 }{ {x}^{2} + 2x } = \frac{(x - 2)(x + 2)}{x(x + 2)} = \frac{x - 2}{x} \: (cu \: x + 2)$

Answer 2

a)4x/6x^2y=2/3xy
simplificând x,4si 6 prin 2
b)(x-3)/3(x-3)=1/3
simplificând x-3
c)(x-2)(x+2)/x(x+2)=
simplificând x+2
(x-2)/x=1-2/x
