This one's ugly.
(5 times the square root of 23 minus 4it)(5 times the square root of 23 plus 4it)
where i is the square root of negative one.

That doesn't factor neatly. Applying the quadratic equation, we find two real solutions: (35 plus or minus the square root of 1237) divided by negative eight.x = -8.7713763487767244x = 0.02137634876724359

Use a factor tree. 575 115,5 23,5,5 5 x 5 x 23 = 575
765 + 575 = 1340
575 + 7% = 575 x (1 + (7/100)) = 575 x 1.07 = 615.25
-16t2 + 64t + 1224 = 0 Multiply both sides by -1 16t2 - 64t - 1224 = 0 Divide both side by 8 2t2 - 8t - 153 = 0 Cannot be factored so use the formula (-b (+ or -)(root of b2 - 4ac)) / 2a
575
16t2 + vt - S = 0 This is in the general form of the quadratic equation, and the general quadratic solution can be applied directly. t = [ (-v) plus or minus the square root of (v2 + 64S) ] all divided by 32.
