Solution for 20x^2+6x^2-7x+1/5x-1 equation:


x in (-oo:+oo)

20*x^2+6*x^2-(7*x)+(1/5)*x-1 = 0

20*x^2+6*x^2-7*x+(1/5)*x-1 = 0

26*x^2-34/5*x-1 = 0

DELTA = (-34/5)^2-(-1*4*26)

DELTA = 3756/25

DELTA > 0

x = ((3756/25)^(1/2)+34/5)/(2*26) or x = (34/5-(3756/25)^(1/2))/(2*26)

x = ((3756/25)^(1/2)+34/5)/52 or x = (34/5-(3756/25)^(1/2))/52

x in { (34/5-(3756/25)^(1/2))/52, ((3756/25)^(1/2)+34/5)/52 }
