You can put this solution on YOUR website! I assume you mean, "solve the following by completing the square:"
3x^2 - 2x + 1 = 5
:
3x^2 - 2x + ___ = 5 - 1
:
3x^2 - 2x + ___ = 4
Coefficient of x^2 has to be 1, divide by 3:
x^2 - x + ___ =
Find the third term to complete the square
x^2 - x + = +
:
x^2 - x + = +
:
x^2 - x + =
:
(x - )^2 =
:
x - = +/-
Two solutions
x = +
x = +
x =
and
x = -
x = -
x =
