To solve the equation ( x^2 + 18x = -13 ), first, rearrange it to form a standard quadratic equation: ( x^2 + 18x + 13 = 0 ). You can then use the quadratic formula ( x = \frac{-b \pm \sqrt{b^2 - 4ac}}{2a} ) with ( a = 1, b = 18, c = 13 ) to find the solutions for ( x ). Calculating the discriminant and applying the formula will yield the values of ( x ).
