Solve this quadratic equation. x2 + 5x + 3 = 0
Solution:
The given quadratic equation can be solved by using the formula which provides the roots of the equation:
\(\frac{-b\pm \sqrt{b^{2}-4ac}}{2a}\)
The above formula is used for solving the quadratic equation of the form ax2 + bx + c
In the given problem:
a = 1; b = 5 and c = 3
Therefore the roots are
\(\frac{-5\pm \sqrt{5^{2}-4(1)(3)}}{2(1)}\)
\(\frac{-5\pm \sqrt{25-12}}{2}\) \(\frac{-5\pm \sqrt{13}}{2}\)
\(\frac{-5}{2} - \frac{\sqrt{13}}{2}\) and \(\frac{-5}{2} + \frac{\sqrt{13}}{2}\)
Solve this quadratic equation. x2 + 5x + 3 = 0
Summary:
On solving the quadratic equation. x2 + 5x + 3 = 0 we get the following roots \(\frac{-5}{2} - \frac{\sqrt{13}}{2}\) and \(\frac{-5}{2} + \frac{\sqrt{13}}{2}\)
