Question

1 Forma descompusa a expresiei algebrice X^2-25
2 Solutiile ecuatiei x^2=49 sunt..... si ......
3In triunghiul ABC dreptunghic in A
4 Rezolvati ecuatia: X supra 2 -x-3 supra 3= x supra 4+1 supra 6
5 Rezolvati in N ecuatia : -3(x-2)+2(3x-5)=6x-2(1-2x)

Answer 1

$1)(x-5)(x+5) \\ 2)x=\pm7 \\ 3) n-am \ text \\ 4) \frac{x}{2} - \frac{x-3}{3} = \frac{x}{4}+ \frac{1}{6} \\ 6x-4x+12=3x+2 \\ x=10 \\ 5) -3x+6+6x-10=6x-2+4x \\ 7x=-2 \\ x=- \frac{2}{7}$
