What are the solutions of 2x2 + 16x + 34 = 0?
Solution:
The given equation is:
2x2 + 16x + 34 = 0
2(x2 + 8x + 17)
The roots of the equation of x2 + 8x + 17 are calculated from the formula
\(\frac{-b\pm \sqrt{b^{2}-4ac}}{2a}\)
Since \({b^{2}-4ac}\) is negative the roots are complex conjugate
=\(\frac{-8\pm \sqrt{8^{2}-4(1)(17)}}{2(1)}\)
=\(\frac{-8\pm \sqrt{64-68}}{2}\)
=\(\frac{-8\pm \sqrt{-4}}{2}\)
=\(\frac{-8\pm 2\sqrt{-1}}{2}\)
=\(\frac{-8\pm 2i}{2}\)
The roots are -4 + i and -4 - i.
What are the solutions of 2x2 + 16x + 34 = 0?
Summary:
The solutions of 2x2 + 16x + 34 = 0 are x = -4 + i and -4 - i.
