Solve 3(w+7)^2=-72, where w is a real number

Mathematics
1 answer:
olga2289 [7]3 years ago
3 0

Answer:

No real solution.

Step-by-step explanation:

We have to solve for the equation:

3(w+7)^2=-72

Now, this can be re-written as:

3(w+7)^2=-72\\=\left(w+7\right)^2=-24

So here we see that the left side of the equation is always a positive term, whereas the right side of the equation is the negative term.  

So here we will never get a real value of w.

This is because the square root of the negative term is a complex number.

So here there is no real solution of the given equation.
