Question

Use the quadratic formula to find the roots of the equation. Round to tenths if necessary. 3x2 - 4x - 8 = 0


A. {-1.7, 2.8}
B. {-2.8, 2}
C. {-1.1, 2.4}
D. no real solution

Answer 1

do you know the quadratic formula?

Answer 2

no

Answer 3

If you have an equation in the form

\(ax^2+bx+c = 0\) where \(a \ne 0\)

the solutions can be found by the quadratic formula, which is

\[x = \frac{-b\pm \sqrt{b^2-4ac}}{2a}\]
