Solution for 63x^7-45x^5-54x^3/9x^3 equation: 


x in (-oo:+oo)

63*x^7-(((54*x^3)/9)*x^3)-(45*x^5) = 0

63*x^7-6*x^6-45*x^5 = 0

63*x^7-6*x^6-45*x^5 = 0

3*x^5*(21*x^2-2*x-15) = 0

21*x^2-2*x-15 = 0

DELTA = (-2)^2-(-15*4*21)

DELTA = 1264

DELTA > 0

x = (1264^(1/2)+2)/(2*21) or x = (2-1264^(1/2))/(2*21)

x = (4*79^(1/2)+2)/42 or x = (2-4*79^(1/2))/42

3*x^5 = 0

3*x^5 = 0 // : 3

x^5 = 0

x = 0

x in { (2-4*79^(1/2))/42, (4*79^(1/2)+2)/42, 0 }
