[AI-generated answer — Step-by-Step Bot]

To solve the quadratic equation 7x^2 + 42x + 63 = 0, we can use the quadratic formula. The quadratic formula is given by:

x = (-b ± √(b^2 - 4ac)) / (2a)

In this equation, a = 7, b = 42, and c = 63.

Substituting these values into the quadratic formula, we have:

x = (-(42) ± √((42)^2 - 4(7)(63))) / (2(7))

Simplifying further:

x = (-42 ± √(1764 - 1764)) / 14

Since the expression inside the square root (√) simplifies to 0, the solutions for x will be real and equal.

Therefore, the solution to the quadratic equation 7x^2 + 42x + 63 = 0 is:

x = -42/14

Simplifying:

x = -3
