Final answer:

To find the value of x in the equation 4x² - 23(92x) = 7, we can rearrange the equation into a quadratic equation and then use the quadratic formula to solve for x. After substituting the values into the formula and simplifying, we find that x can take on two possible values: 0 or 529.5.

Step-by-step explanation:

We can rearrange the equation to form a quadratic equation:

4x² - 23(92x) = 7

4x² - 2116x = 7

Now we can solve the quadratic equation by using the quadratic formula:

x = (-b ± sqrt(b² - 4ac)) / (2a)

For this equation, a = 4, b = -2116, and c = -7.

After substituting these values into the formula, we can solve for x:

x = (2116 ± sqrt((-2116)² - 4(4)(-7))) / (2(4))

Simplifying further:

x = (2116 ± sqrt(4467456 - (-112))) / 8

x = (2116 ± sqrt(4467568)) / 8

x = (2116 ± 2116) / 8

Now we have two possible values for x:

x = 0

or

x = 529.5
