Question
solve for w.
-12 = w + \frac{27}{w}
if there is more than one solution, separate them with commas
if there is no solution, click on
o solution\.
Step1: Eliminate the denominator
Multiply both sides of the equation \(-12 = w+\frac{27}{w}\) by \(w\) (assuming \(w
eq0\)) to get rid of the fraction. We obtain \(-12w = w^{2}+27\).
Step2: Rearrange into standard quadratic form
Rearrange the equation \(-12w = w^{2}+27\) to the standard quadratic form \(ax^{2}+bx + c = 0\). So we have \(w^{2}+12w + 27=0\).
Step3: Factor the quadratic equation
Factor the quadratic expression \(w^{2}+12w + 27\). We need two numbers that multiply to \(27\) and add up to \(12\). The numbers are \(3\) and \(9\). So, \(w^{2}+12w + 27=(w + 3)(w+9)=0\).
Step4: Solve for \(w\)
Set each factor equal to zero and solve for \(w\).
- For \(w + 3=0\), we get \(w=-3\).
- For \(w + 9=0\), we get \(w=-9\).
We need to check if these solutions are valid (since we multiplied by \(w\) earlier, we must ensure \(w
eq0\), and both \(-3\) and \(-9\) are not zero, so they are valid.
