Answer :
Simplifying
10000x2 + -64 = 0
Reorder the terms:
-64 + 10000x2 = 0
Solving
-64 + 10000x2 = 0
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '64' to each side of the equation.
-64 + 64 + 10000x2 = 0 + 64
Combine like terms: -64 + 64 = 0
0 + 10000x2 = 0 + 64
10000x2 = 0 + 64
Combine like terms: 0 + 64 = 64
10000x2 = 64
Divide each side by '10000'.
x2 = 0.0064
Simplifying
x2 = 0.0064
Take the square root of each side:
x = {-0.08, 0.08}
