If you first distribute you see that it would be 9x+27=-8+x if you move the terms around its 8x=-35 so x=-35/8 or -4.375

If you first factor this equation you find that its (x-4)(x-1) so x=4 and x=1.

If you check both you see that they are both true so the solutions are 4 and 1.

This would be if you set up the equation it would look like this $\frac{2x}{x+2}=\frac{x}{x-4}$ if you cross-multiply you would get $2{x}^{2}-8x={x}^{2}+2x$ once you simplify you see its ${x}^{2}-10x$ once you factor x out $x(x-10)$ so the answers would be x=0 and x=10 and if you check this both solutions work for this.

The answers are x=10 and x=0

If we put this in the form a+bi 

We first start by doing $\sqrt{3}*\sqrt{-6}=\sqrt{3}*\sqrt{3}*\sqrt{-2}$ so this would result in the answer being $3\sqrt{-2}$ or $3\sqrt{2}i$ so 

B= $3\sqrt{2}i$

So then solving for 6i*i then we know that ${i}^{2}$ is equal to -1 so we know that -6.

This means that it would be -6+ $3\sqrt{2}i$
