It depends on what precisely the question is.
One possible answer is that the quadratic expression has a value of 2 when x = 0.
(9x)2 +9x/(45x)2 +81= 9+9x/86

x - 10x = 9x, so 9x + 3 = 0, so 9x = -3 so x = -1/3
0
-10x+3 = -x+12 -10x+x = 12-3 -9x = 9 x = -1
x2 + 9x2 = 10x2
-38-10x = 9x+19 -38-19 = 9x+10x -57 = 19x |: 19 -3 = x Therefore x equals -3
9x + 1x = 10x.
(9x)2 +9x/(45x)2 +81= 9+9x/86
9x squared plus 16 = 0 factored is plus and minus 4/3 i.
9x^(2) + 16 DOES NOT factor. Remember ; two squared terms with a plus(+) between them DOES NOT factor However, two squared terms with a minus(-) between them DOES factor . Hence 9x^(2) + 16 = (3x)^2) + 4^(2) does NOT factor However, 9x^(2) - 16 = (3x)^2) - 4^(2) does factor to ( (3x - 4)(3x + 4) Note the two different signs.

x - 10x = 9x, so 9x + 3 = 0, so 9x = -3 so x = -1/3
10x = 9x -25 10x -9x = -25 x = -25
x + 20 + 10x = 20 + 9x 11x + 20 = 20 + 9x Subtract 20 from both sides: 11x = 9x Subtract 9x from both sides: 2x = 0 Divide both sides by 2: x = 0

-10x+3 = -x+12 -10x+x = 12-3 -9x = 9 x = -1
