9x^2 + 2^2 = 0
3x +2 = 0
therefore: x=-2/3
(9x)2 +9x/(45x)2 +81= 9+9x/86
It can't be solved because the discriminant of the given quadratic equation is less than zero meaning it has no real roots.
9x squared plus 16 = 0 factored is plus and minus 4/3 i.
It can't be factored because the discriminant of this quadratic expression is less than zero.
If you mean: x2+9x+20 then it is (x+4)(x+5) = 0 when factored
It has no solutions because the discriminant is less than zero.
(9x)2 +9x/(45x)2 +81= 9+9x/86
x = ±2
9x squared plus 16 = 0 factored is plus and minus 4/3 i.
are you sure from this equation ? x^2 + 9x + 11 ____________ = zero x + 7 or there is no zero ?? please be sure from the x^2 + 9x + 11 ???

(9x2 + 7)(9x2 - 7) = 81x4 - 49
(9x + 7)(x - 2)
63x2+76x+21 = 0 (7x+3)(9x+7) = 0 x = -3/7 or x = -7/9
