Simplifying
X2 + -11x + 16 = 0
Reorder the terms:
16 + X2 + -11x = 0
Solving
16 + X2 + -11x = 0
Solving for variable 'X'.
Move all terms containing X to the left, all other terms to the right.
Add '-16' to each side of the equation.
16 + X2 + -16 + -11x = 0 + -16
Reorder the terms:
16 + -16 + X2 + -11x = 0 + -16
Combine like terms: 16 + -16 = 0
0 + X2 + -11x = 0 + -16
X2 + -11x = 0 + -16
Combine like terms: 0 + -16 = -16
X2 + -11x = -16
Add '11x' to each side of the equation.
X2 + -11x + 11x = -16 + 11x
Combine like terms: -11x + 11x = 0
X2 + 0 = -16 + 11x
X2 = -16 + 11x
Simplifying
X2 = -16 + 11x
Reorder the terms:
16 + X2 + -11x = -16 + 11x + 16 + -11x
Reorder the terms:
16 + X2 + -11x = -16 + 16 + 11x + -11x
Combine like terms: -16 + 16 = 0
16 + X2 + -11x = 0 + 11x + -11x
16 + X2 + -11x = 11x + -11x
Combine like terms: 11x + -11x = 0
16 + X2 + -11x = 0
The solution to this equation could not be determined.
