z^2-8z+35=

Solution for z^2-8z+35= equation:

Simplifying
z2 + -8z + 35 = 0

Reorder the terms:
35 + -8z + z2 = 0

Solving
35 + -8z + z2 = 0

Solving for variable 'z'.

Begin completing the square.

Move the constant term to the right:

Add '-35' to each side of the equation.
35 + -8z + -35 + z2 = 0 + -35

Reorder the terms:
35 + -35 + -8z + z2 = 0 + -35

Combine like terms: 35 + -35 = 0
0 + -8z + z2 = 0 + -35
-8z + z2 = 0 + -35

Combine like terms: 0 + -35 = -35
-8z + z2 = -35

The z term is -8z.  Take half its coefficient (-4).
Square it (16) and add it to both sides.

Add '16' to each side of the equation.
-8z + 16 + z2 = -35 + 16

Reorder the terms:
16 + -8z + z2 = -35 + 16

Combine like terms: -35 + 16 = -19
16 + -8z + z2 = -19

Factor a perfect square on the left side:
(z + -4)(z + -4) = -19

Can't calculate square root of the right side.
