Question 166183: Please check my answers for in quadratic formula:
solve: v^2 = 12v - 24
v^2 12v + 24 = 0
v = 12 =/- sqr. rt. of 12^2 - 4(24)/2
= 12 +/- sqr. rt of 144 - 96/2
= 12 sqr. rt of 48/2
= 12 sqr. rt. of 4*4*3/2
= 12 +/- 4 sqr. rt. of 3/2
answer: 6 - 4 sqrt rt. of 3, 6 + 4 sqr. rt. of 3

You can put this solution on YOUR website!
v+=+%2812+%2B-+sqrt%2812%5E2+-+4%2824%29%29%29%2F2
v+=+%2812+%2B-+sqrt%28144-96%29%29%2F2
v+=+%2812+%2B-+sqrt%2848%29%29%2F2
v+=+%2812+%2B-+4%2Asqrt%283%29%29%2F2
You missed a division by 2 in front of the square root.
v+=+6+%2B-+highlight%282%29%2Asqrt%283%29
