Question

(2x+1) la patrat + (2x+2) la patrat =(2x+3) la patrat

Answer 1

(2x+1)(2x+1)=4 x la 2 +4x+1
(2x+2)(2x+2)=4 x la2+8x+4
(2x+3)(2x+3)=4 x la2+12x+9

4 x la 2 +4x+1+4 x la 2+8x+4=4x la 2+12x+9
8x la2-+12x+5=4x la2 +12x+9
8xla2-4xla2+12x-12x+5-9=
4x la2-4=(2x+2)(2x-2)

Answer 2

(2x+1)^2+(2x+2)^2=(2x+3)^2
4x^2+4x+1+4x^2+8x+4=4x^2+12x+9
4x+1+4x^2+8x+4=12x+9
12x+5+4x^2=12x+9
5+4x^2=9
4x^2=9-5
4x^2=4
x^2=1
x=plus,minus1
x=1
x=-1
x1=-1,X2=1
