Simplifying
F(0) = 11 + -4x2
Reorder the terms for easier multiplication:
0F = 11 + -4x2
Anything times zero is zero.
0F = 11 + -4x2
Solving
0 = 11 + -4x2
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '4x2' to each side of the equation.
0 + 4x2 = 11 + -4x2 + 4x2
Remove the zero:
4x2 = 11 + -4x2 + 4x2
Combine like terms: -4x2 + 4x2 = 0
4x2 = 11 + 0
4x2 = 11
Divide each side by '4'.
x2 = 2.75
Simplifying
x2 = 2.75
Take the square root of each side:
x = {-1.658312395, 1.658312395}
