To solve the equation X^2 + X - 61 = -5, we need to simplify it first by adding 5 to both sides of the equation, which gives us X^2 + X - 56 = 0.

We can then use the quadratic formula to solve for X, which is:

X = (-b ± √(b^2 - 4ac)) / 2a

In this case, a = 1, b = 1, and c = -56.

Plugging these values into the quadratic formula, we get:

X = (-1 ± √(1^2 - 4(1)(-56))) / 2(1)

X = (-1 ± √(1 + 224)) / 2

X = (-1 ± √225) / 2

X = (-1 ± 15) / 2

So the two possible values of X are:

X = (-1 + 15) / 2 = 7

X = (-1 - 15) / 2 = -8

Therefore, X can be either 7 or -8.
