Solution for 3t^2+8t+5=-2t^2 equation:


Simplifying
3t2 + 8t + 5 = -2t2

Reorder the terms:
5 + 8t + 3t2 = -2t2

Solving
5 + 8t + 3t2 = -2t2

Solving for variable 't'.

Combine like terms: 3t2 + 2t2 = 5t2
5 + 8t + 5t2 = -2t2 + 2t2

Combine like terms: -2t2 + 2t2 = 0
5 + 8t + 5t2 = 0

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

Divide each side by '5'.
1 + 1.6t + t2 = 0

Move the constant term to the right:

Add '-1' to each side of the equation.
1 + 1.6t + -1 + t2 = 0 + -1

Reorder the terms:
1 + -1 + 1.6t + t2 = 0 + -1

Combine like terms: 1 + -1 = 0
0 + 1.6t + t2 = 0 + -1
1.6t + t2 = 0 + -1

Combine like terms: 0 + -1 = -1
1.6t + t2 = -1

The t term is 1.6t.  Take half its coefficient (0.8).
Square it (0.64) and add it to both sides.

Add '0.64' to each side of the equation.
1.6t + 0.64 + t2 = -1 + 0.64

Reorder the terms:
0.64 + 1.6t + t2 = -1 + 0.64

Combine like terms: -1 + 0.64 = -0.36
0.64 + 1.6t + t2 = -0.36

Factor a perfect square on the left side:
(t + 0.8)(t + 0.8) = -0.36

Can't calculate square root of the right side.

The solution to this equation could not be determined.
