-х^2=-49

To solve the equation -x^2 = -49, we can begin by isolating x^2 by itself. We can do this by multiplying both sides of the equation by -1:

(-1)(-x^2) = (-1)(-49) x^2 = 49

Now, to find the value of x, we can take the square root of both sides of the equation:

√(x^2) = √49 x = ±7

So, the solution to the equation -x^2 = -49 is x = -7 or x = 7.
