Solve for $𝑥$. If there are multiple answers, separate them with commas. Give answers as fractions and not decimals.
$\frac{3}{10000}x^2-\frac{7}{100}x+4=0$
$\left(x+3\right)^2=\frac{x+3}{2}+3$
$x^2-\left(\sqrt{2}+\sqrt{3}\right)x+\sqrt{6}=0$
$x^2-\left(a-2\right)x-2a=0$ (where $a$ is a constant)
$ax^2-\left(a+b\right)x+b=0$ (where $a$ and $b$ are constants)
$\left(a-1\right)x^2-\left(a^2-1\right)x=0$ (where $a$ is a constant)
The quadratic equation $x^2+2ax-3a=0$ has 2 solutions. One of the solutions is $x=-3$. Find $a$ and the other value of $x$.
