9-2e(3-5e)=

Solution for 9-2e(3-5e)= equation:

Simplifying
9 + -2e(3 + -5e) = 0
9 + (3 * -2e + -5e * -2e) = 0
9 + (-6e + 10e2) = 0

Solving
9 + -6e + 10e2 = 0

Solving for variable 'e'.

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

Divide each side by '10'.
0.9 + -0.6e + e2 = 0.0

Move the constant term to the right:

Add '-0.9' to each side of the equation.
0.9 + -0.6e + -0.9 + e2 = 0.0 + -0.9

Reorder the terms:
0.9 + -0.9 + -0.6e + e2 = 0.0 + -0.9

Combine like terms: 0.9 + -0.9 = 0.0
0.0 + -0.6e + e2 = 0.0 + -0.9
-0.6e + e2 = 0.0 + -0.9

Combine like terms: 0.0 + -0.9 = -0.9
-0.6e + e2 = -0.9

The e term is -0.6e.  Take half its coefficient (-0.3).
Square it (0.09) and add it to both sides.

Add '0.09' to each side of the equation.
-0.6e + 0.09 + e2 = -0.9 + 0.09

Reorder the terms:
0.09 + -0.6e + e2 = -0.9 + 0.09

Combine like terms: -0.9 + 0.09 = -0.81
0.09 + -0.6e + e2 = -0.81

Factor a perfect square on the left side:
(e + -0.3)(e + -0.3) = -0.81

Can't calculate square root of the right side.

The solution to this equation could not be determined.
