Question

Solve using the quadratic formula. (answer in simplest exact values). 3x^2-2=-4x

Answer 1

I have gotten up to x=-4± √40/6 ... just unclear on how to simplify further

Answer 2

Simplify the radical. You can divid a perfect square out of it.

Answer 3

in other words
\[40=4\times 10\] so
\[\sqrt{40}=\sqrt{4\times 10}=\sqrt4\sqrt{10}=2\sqrt{10}\]

Answer 4

factor out the common factor of \(2\) in the numerator
then cancel
