Answer 3

Solving the Equation 7x^2 + 1 = 0

To solve the equation 7x^2 + 1 = 0, we can use the quadratic formula, which 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)

In this case, a = 7, b = 0, and c = 1. Plugging these values into the quadratic formula, we get:

x = (-0 ± √(0^2 - 4*7*1)) / (2*7)

Solving this equation will give us the solutions for x.

Solution

The solutions for the equation 7x^2 + 1 = 0 are:

x = ±i√7/7

This means that the solutions are complex numbers, specifically imaginary numbers.
