$2x\times6x\times101+1=12\times x102x\times333+516-25$

$12x{}^{2}\times101+1=12\times x102x\times333+516-25$

$1212x{}^{2}+1=12\times x102x\times333+516-25$

$1212x{}^{2}+1=12\times 102x{}^{2}\times333+516-25$

$1212x{}^{2}+1=1224x{}^{2}\times333+516-25$

$1212x{}^{2}+1=40592x{}^{2}+516-25$

$1212x{}^{2}+1=40592x{}^{2}+491$

$1=39380x{}^{2}+491$

$-490=39380x{}^{2}$

$\frac{-490}{39380}=x{}^{2}$

$-\frac{490}{39380}=x{}^{2}$

$x{}^{2}=-\frac{490}{39380}$

$x{}^{2}=-\frac{49}{3938}$

$x≈ 0.1115475880428244i$ or $x≈-0.1115475880428244i$

Could u put spaces in between each function so I may decipher it better plz...

That is better, it looks complicated when it is really quite simple when u put it like that...
