7t^2(t-t^2+5t^3)=

Solution for 7t^2(t-t^2+5t^3)= equation:

Simplifying
7t2(t + -1t2 + 5t3) = 0
(t * 7t2 + -1t2 * 7t2 + 5t3 * 7t2) = 0
(7t3 + -7t4 + 35t5) = 0

Solving
7t3 + -7t4 + 35t5 = 0

Solving for variable 't'.

Factor out the Greatest Common Factor (GCF), '7t3'.
7t3(1 + -1t + 5t2) = 0

Ignore the factor 7.
Subproblem 1
Set the factor 't3' equal to zero and attempt to solve:

Subproblem 2
Set the factor '(1 + -1t + 5t2)' equal to zero and attempt to solve:

Simplifying
1 + -1t + 5t2 = 0

Solving
1 + -1t + 5t2 = 0

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

Divide each side by '5'.
0.2 + -0.2t + t2 = 0

Move the constant term to the right:

Add '-0.2' to each side of the equation.
0.2 + -0.2t + -0.2 + t2 = 0 + -0.2

Reorder the terms:
0.2 + -0.2 + -0.2t + t2 = 0 + -0.2

Combine like terms: 0.2 + -0.2 = 0.0
0.0 + -0.2t + t2 = 0 + -0.2
-0.2t + t2 = 0 + -0.2

Combine like terms: 0 + -0.2 = -0.2
-0.2t + t2 = -0.2

The t term is -0.2t.  Take half its coefficient (-0.1).
Square it (0.01) and add it to both sides.

Add '0.01' to each side of the equation.
-0.2t + 0.01 + t2 = -0.2 + 0.01

Reorder the terms:
0.01 + -0.2t + t2 = -0.2 + 0.01

Combine like terms: -0.2 + 0.01 = -0.19
0.01 + -0.2t + t2 = -0.19

Factor a perfect square on the left side:
(t + -0.1)(t + -0.1) = -0.19

Can't calculate square root of the right side.
