We have that

x²<span>-8x=39

</span>

<span>Group terms that contain the same variable</span>

(x²-8x)=39

Complete
the square. Remember to balance the equation by adding the same constants
to each side

(x²-8x+16)=39+16

Rewrite as perfect squares

(x-4)²=55-------> (x-4)²-55=0

(+/-)]x-4]=√55

(+)]x-4]=√55--------> x=4+√55

(-)]x-4]=√55-------> x=4-√55

**the answer is**

** (x-4)²-55=0**
