x in (-oo:+oo)

(x+2)^2-(16/25) = 0

(x+2)^2-16/25 = 0

(25*(x+2)^2)/25-16/25 = 0

25*(x+2)^2-16 = 0

25*x^2+100*x+84 = 0

25*x^2+100*x+84 = 0

25*x^2+100*x+84 = 0

DELTA = 100^2-(4*25*84)

DELTA = 1600

DELTA > 0

x = (1600^(1/2)-100)/(2*25) or x = (-1600^(1/2)-100)/(2*25)

x = -6/5 or x = -14/5

(x+14/5)*(x+6/5) = 0
