Final answer:
To solve a quadratic equation, you can use the quadratic formula or complete the square. The equation x^2 + 5x + 3 can be solved using the quadratic formula.
Step-by-step explanation:
This equation is a quadratic equation. To solve it, we can use the quadratic formula or complete the square. For the quadratic formula, the equation is in the form ax^2 + bx + c = 0, where a = 1, b = 5, and c = 3. Plugging these values into the quadratic formula, we get:
x = (-b ± √(b^2 - 4ac)) / (2a)
Substituting the values of a, b, and c, we have:
x = (-5 ± √(5^2 - 4(1)(3))) / (2(1))
Solving this equation gives us two possible values for x.
