-28t + 7t2 + -2t(3 + -4t + 8t2) = 0
-28t + 7t2 + (3 * -2t + -4t * -2t + 8t2 * -2t) = 0
-28t + 7t2 + (-6t + 8t2 + -16t3) = 0

Reorder the terms:
-28t + -6t + 7t2 + 8t2 + -16t3 = 0

Combine like terms: -28t + -6t = -34t
-34t + 7t2 + 8t2 + -16t3 = 0

Combine like terms: 7t2 + 8t2 = 15t2
-34t + 15t2 + -16t3 = 0

Solving
-34t + 15t2 + -16t3 = 0

Solving for variable 't'.

Factor out the Greatest Common Factor (GCF), 't'.

Subproblem 2
Set the factor '(-34 + 15t + -16t2)' equal to zero and attempt to solve:

Simplifying
-34 + 15t + -16t2 = 0

Solving
-34 + 15t + -16t2 = 0

Begin completing the square.  Divide all terms by
-16 the coefficient of the squared term: 

Divide each side by '-16'.
2.125 + -0.9375t + t2 = 0

Move the constant term to the right:

Add '-2.125' to each side of the equation.
2.125 + -0.9375t + -2.125 + t2 = 0 + -2.125

Reorder the terms:
2.125 + -2.125 + -0.9375t + t2 = 0 + -2.125

Combine like terms: 2.125 + -2.125 = 0.000
0.000 + -0.9375t + t2 = 0 + -2.125
-0.9375t + t2 = 0 + -2.125

Combine like terms: 0 + -2.125 = -2.125
-0.9375t + t2 = -2.125

The t term is -0.9375t.  Take half its coefficient (-0.46875).
Square it (0.2197265625) and add it to both sides.

Add '0.2197265625' to each side of the equation.
-0.9375t + 0.2197265625 + t2 = -2.125 + 0.2197265625

Reorder the terms:
0.2197265625 + -0.9375t + t2 = -2.125 + 0.2197265625

Combine like terms: -2.125 + 0.2197265625 = -1.9052734375
0.2197265625 + -0.9375t + t2 = -1.9052734375

Factor a perfect square on the left side:
(t + -0.46875)(t + -0.46875) = -1.9052734375

Can't calculate square root of the right side.
