Final answer:

The expression X²+14X+3 is a quadratic equation with solutions x ≈ -0.536 or x ≈ -13.464.

Step-by-step explanation:

The expression X²+14X+3 is a quadratic equation of the form ax² + bx + c, where a = 1, b = 14, and c = 3.

To find the solutions to this quadratic equation, we can use the quadratic formula:

x = (-b ± √(b² - 4ac)) / (2a)

Substituting the values of a, b, and c into the quadratic formula, we get:

x = (-14 ± √(14² - 4(1)(3))) / (2(1))

Simplifying further, we have:

x = (-14 ± √(196 - 12)) / 2

x = (-14 ± √(184)) / 2

Since √(184) is not a rational number, we cannot simplify it any further. Therefore, the solutions to the quadratic equation are approximately:

x ≈ -0.536 or x ≈ -13.464
