Subproblem 1
Set the factor 'x' equal to zero and attempt to solve:

Simplifying
x = 0

Solving
x = 0

Move all terms containing x to the left, all other terms to the right.

Simplifying
x = 0
Subproblem 2
Set the factor '(8 + -3x + 5x2)' equal to zero and attempt to solve:

Simplifying
8 + -3x + 5x2 = 0

Solving
8 + -3x + 5x2 = 0

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

Divide each side by '5'.
1.6 + -0.6x + x2 = 0

Move the constant term to the right:

Add '-1.6' to each side of the equation.
1.6 + -0.6x + -1.6 + x2 = 0 + -1.6

Reorder the terms:
1.6 + -1.6 + -0.6x + x2 = 0 + -1.6

Combine like terms: 1.6 + -1.6 = 0.0
0.0 + -0.6x + x2 = 0 + -1.6
-0.6x + x2 = 0 + -1.6

Combine like terms: 0 + -1.6 = -1.6
-0.6x + x2 = -1.6

The x term is -0.6x.  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.
-0.6x + 0.09 + x2 = -1.6 + 0.09

Reorder the terms:
0.09 + -0.6x + x2 = -1.6 + 0.09

Combine like terms: -1.6 + 0.09 = -1.51
0.09 + -0.6x + x2 = -1.51

Factor a perfect square on the left side:
(x + -0.3)(x + -0.3) = -1.51

Can't calculate square root of the right side.
