Answer 2

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.
