How is everyone this November morning? I just need some help today with some polynomial problems that are tricky for me.
what are the roots/zeros of 2x^2+4x+7?
(Hint: this one will not factor, so you will have to use something else…)
Please and thank you! 0^>
If the polynomial (quadratic) will not factor, then use the Quadratic formula
\(x = {-b \pm \sqrt{b^2-4ac} \over 2a}\)
We will have to assume 2x^2+4x+7 = 0 SInce you are looking for roots
For this a = 2 b = 4 c = 7
-4 +-sqrt(-40) / 4 = -1 +- 1/2 i sqrt (10)
