we have
Solve for w means that clear variable w
Group terms that contain the variable w, and move the other terms to the opposite side of the equation
Factor the variable w
Divide both sides by 
therefore
<u>the answer is</u>
You said that (xy) = 16, and (x+y) = 4 .
From the second equation you can get [ x = 4 - y ],
then substitude that for 'x' in the first equation, and
finally, rearrange the first equation to read
<u>x² - 4x + 16 = 0</u>
Don't even try to factor that quadratic equation. Go straight
to the quadratic formula, and the two solutions you find are ...
<em>x = 2 + i 2√3</em>
and
<em>x = 2 - i 2√3</em> .
Those are the two number that do what you want.
There are no <u>real</u> numbers that can do it.
The nth root of a is always positive unless, a < 0 and "n" is an odd number. Also if a < 0 <span> and "n" is an even number, then it's an imaginary number. I hope this helps a lot</span>
