Question

(x+2) puterea 2 supra 2 - ( x-3) ( x+3) supra 3= 2x-1 supra 2 + ( x-1)  puterea 2 supra 6 .. URGENTT vaa rogg

Answer 1

(x+2)²=x²+4x+4
(x+3)(x-3)=x²-9
(x-1)²=x²-2x+1

x²+4x+4 /2   -(x²-9)/3=2x-1/2   + x²-2x+1/6    aducem la acelasi numitor
3x²+12x+12-2x²+18=6x-3+x²-2x+1
x²+12x+30=x²+4x-2
12x+30=4x-2
12x-4x=-2-30
8x=-32
x=-4

Answer 2

x+1=2x : 6 =>
2x*x+1=6 =>
3x+1=6=>
6:3-1=x=>
x=1
