Straight to the quadratic equation. -b +/- sqrt(b^2 - 4ac)/2a

16 = a

-24 = b

7 = c

24 +/- sqrt[ (-24)^2 - 4(16)(7)]/2(16)

24 +/-sqrt( 576-448)/32

24 +/- sqrt(128)/32 ( reduce fraction )

3 +/- sqrt(128)/4 ( let us see about that mess under the radical )( like this!)

3 +/- sqrt( 4^2 * 2^2 * 2)/4 (4 and 2 come out and make 8)

3 +/- 8sqrt(2)/4 ( you finish)
