Answer:To solve the equation x^2 + x - 126 = 0, we can use the quadratic formula or factoring method.

Let's use the quadratic formula to find the solutions:

Step 1: Identify the coefficients:

a = 1 (coefficient of x^2)

b = 1 (coefficient of x)

c = -126 (constant term)

Step 2: Apply the quadratic formula:

The quadratic formula states that for an equation of the form ax^2 + bx + c = 0, the solutions for x are given by:

x = (-b ± √(b^2 - 4ac)) / (2a)

Plugging in the values from our equation:

x = (-1 ± √(1^2 - 4(1)(-126))) / (2(1))

Simplifying:

x = (-1 ± √(1 + 504)) / 2

x = (-1 ± √505) / 2

So, the solutions to the equation x^2 + x - 126 = 0 are:

x = (-1 + √505) / 2

x = (-1 - √505) / 2
