    Ok the answer is 5x2 is 10 and then minus 2-4 is 2 and then 4x+2 is 6

    When you have a quadratic with 1 as the coefficient of the x^2 term, to complete the square, take half of the x-term coefficient, and square it.

    x^2 - 4x doe have a 1 as the coefficient of the x^2 term. The coefficient of the x term is -4. Take half of -4. Then square that.

    No. The complete the square term is always positive. Half of -4 is -2 -2 squared is 4. The answer is 4.

    6 is incorrect. The complete the square term has to be a perfect square. 6 is not a perfect square, so 6 cannot possibly be correct.

    So then it is 4 because 4 is a perfect square, and i believe mathstudent55
