Final answer:
To find x in the equation -39 + x - 146 = 0, we can use the quadratic formula. Plugging in the values, we get x ≈ -14.1 or 13.1.
Step-by-step explanation:
To find x in the equation -39 + x - 146 = 0, we can use the quadratic formula:
x = (-b ± √(b^2 - 4ac)) / (2a)
Plugging in the values from the equation, we get:
a = 1, b = 1, and c = -185
Substituting these values into the formula gives us:
x = (-1 ± √(1^2 - 4(1)(-185))) / 2(1)
Simplifying further:
x = (-1 ± √(1 + 740)) / 2
x = (-1 ± √741) / 2
Approximating the square root of 741 gives us:
x ≈ (-1 ± 27.2) / 2
Therefore, x could be approximately -14.1 or 13.1.
