Final answer:

The quadratic equation 4 + x^2 = 7x can be solved by rearranging it into standard form x^2 - 7x + 4 = 0 and then using the quadratic formula. The solutions are x = (7 + √33) / 2 and x = (7 - √33) / 2.

Step-by-step explanation:

To solve the quadratic equation 4 + x^2 = 7x, we first need to rearrange it into the standard quadratic form

ax^2 + bx + c = 0.

Subtracting 7x from both sides, we obtain x^2 - 7x + 4 = 0.

Now, we can apply the quadratic formula:

x = (-b ± √(b^2 - 4ac)) / (2a)

For our equation, a = 1, b = -7, and c = 4.

Plugging these values into the quadratic formula, we get:

x = (7 ± √(49 - 16)) / 2

x = (7 ± √33) / 2

Therefore, the two solutions for x are x = (7 + √33) / 2 and x = (7 - √33) / 2.
