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.
16t2 - 37t + 20 = 0 Using the quadratic formula, t = [37 +/- sqrt(372 - 4*16*20)]/(2*16) = [37 +/- sqrt(89)] / 32 ie t = 0.861438 or t = 1.451062
For "6t - (2t2)", it is not reducible. For "(6t - 2t2)", it is 16t2
16t(t + 4) is the factorization Usually it's set = to 0 16t (t+4) =0 So, either 16t = 0 or t + 4 = 0 t = 0 or t = -4
4 plus 10 plus 16 plus 70 equals 100. To find the sum of this series, simply add all the numbers together.
