Question

the quadratic equation x2 - 4x + 57 = -5 by completing the square

Answer 1

Move 57 to the other side of the eq so you have x^2-4x =-62

Answer 2

Then take half of the "b" term, -4/2=-2. Square it, 4.
Add to both sides of eq & factor
X,^2-4x+4=-62

Answer 3

(X-2)(X-2) or (X-2)^2=-62
Find the sq rt of each side.
X-2=sq rt of -62
X-2 = i(sq rt 62)
x = 2+i(Sq rt 62)
