Question

find all complex solutions 4x^2+2x-1=0

Answer 1

Use your Quadratic Formula:\[\large\rm x=\frac{-b\pm\sqrt{b^2-4ac}}{2a}\]

Answer 2

\[\large\rm x=\frac{-2\pm\sqrt{(2)^2-4(4)(-1)}}{2(4)}\]

Answer 3

Hmm there are only real solutions to this polynomial,
no complex.

Answer 4

i have been working on this(solving quadratic equations with coplex roots) for hours i just cant figure it out

Answer 5

Two real roots, maybe it's intended to be \[4x^2+2x+1\]
