Question

Uprość wyrażenie:
[tex]\frac{4x- 12}{2x^{2} - 12x+ 18}[/tex]

[tex]\frac{3x - 9}{2x^{2} - 5x - 3}[/tex]

Answer 1

Odpowiedź:

[tex] \frac{4x - 12}{2 {x}^{2} - 12x + 18 } = \frac{4(x - 3)}{2( {x}^{2} - 6x + 9) } = \frac{4(x - 3)}{2 {(x - 3)}^{2} } = \frac{2(x - 3)}{ {(x - 3)}^{2} } = \frac{2}{x - 3} [/tex]

[tex] \frac{3x - 9}{2 {x}^{2} - 5x - 3 } = \frac{3(x - 3)}{2 {x}^{2} - 2x - 3x - 3 } = \frac{3(x - 3)}{2x(x - 1) - 3(x + 1)} [/tex]
