Your equation is not clear
I can understand it in two ways
(x2-16)/x-4+x2=16
x=-4.59486 x=-0.793499 x=4.38835
or
x2-(16/x)-4+x2=16
x=3.50466 x=-0.864641 x=-2.64002

It is a quadratic equation with one unknown variable, x which has no real roots.
Dividend: x3+4x2-9x-36 Divisor: x+3 Quotient: x2+x-12
Use the quadratic formula, with a = 1, b = -3, c = 2.
Please resubmit your question spelling out the symbols as "plus", "minus", "times", "divided by", "equals", "squared", "cubed" etc. Please use "brackets" (or parentheses) because it is impossible to work out whether "x plus y squared" means x + y^2 or (x + y)^2. You will need to use a code, for example b1 (open bracket) and b2 (close bracket), because the browser will reject brackets!Here, it is not clear whether you mean 2^a + 3 or 2^(a+3)
