Tolong jawab nomor 6-9 penting banget.... Question from @NisaDeswani28

Matrixisme 6) $\frac{x}{x+y}$ + $\frac{y}{x-y}$ = $\frac{x(x-y)}{(x+y)(x-y)}$ + $\frac{y(x+y)}{(x-y)(x+y)}$ = $\frac{x(x-y)+y(x+y)}{(x-y)(x+y)}$ = $\frac{x^{2}-xy+xy+y^{2}}{x^{2}-y^{2}}$ = $\frac{x^{2}+y^{2}}{x^{2}-y^{2}}$

7) $\frac{\frac{x^{2}+y^{2}}{x+y}}{\frac{x}{y}+\frac{y}{x}}$ = $\frac{\frac{x^{2}+y^{2}}{x+y}}{\frac{x(x)}{y(x)}+\frac{y(y)}{x(y)}}$ = $\frac{\frac{x^{2}+y^{2}}{x+y}}{\frac{x(x)+y(y)}{y(x)}$ = $\frac{x^{2}+y^{2}}{x+y}$ : $\frac{x(x)+y(y)}{y(x)} = [tex]\frac{x^{2}+y^{2}}{x+y}$ x $\frac{y(x)}{x(x)+y(y)}$ = $\frac{x^{2}+y^{2}}{x+y}$ x $\frac{xy}{x^{2}+y^{2}}$ = $\frac{xy}{x+y}$

8) $\frac{x^{2}-5x-6}{x+1}$ = $\frac{(x-6)(x+1)}{x+1}$ = x - 6

9) $\frac{3x^{2}-27}{x^{2}+2x-3}$ = $\frac{3(x^{2}-9)}{(x-1)(x+3)}$ = $\frac{3(x-3)(x+3)}{(x-1)(x+3)}$ = $\frac{3(x-3)}{(x-1)}$ = $\frac{3x-9}{x-1}$
