X*(x-1) = 56

To solve for X, we need to expand the left side of the equation:

X x - X 1 = 56

Now we simplify:

X^2 - X = 56

Next, we set the equation equal to 0:

X^2 - X - 56 = 0

Now, we can factor the quadratic equation:

(X - 8)(X + 7) = 0

Setting each factor to zero gives us the possible solutions for X:

X - 8 = 0 or X + 7 = 0

X = 8 or X = -7

Therefore, the solutions for X are X = 8 and X = -7.
