help me Use the Quadratic Formula to solve N2=6n

  • 11th grade-math -

    n^2 = n.

    n^2 - n = 0,
    n = (-b+-sqrt(b^2-4ac)) / 2a.
    n = (1+-sqrt(1-4*1*0)0 / 2,
    n = (1+-sqrt(1-0)) / 2,
    n = (1+-1) / 2,
    n = (1+1) / 2 = 1.
    n = (1-1) / 2 = 0/2 = 0.

    Solution set: n = 1, and 0.

    Correction:
    n^2 = 6n.

    n^2 - 6n = 0,
    n = (6 +- sqrt(36-4*1*0)) / 2,
    n = (6 +- sqrt(36-0)) / 2,
    n = (6 +-sqrt(36)) / 2,
    n = (6 +- 6) / 2,
    n = (6+6) / 2 = 6.
    n = (6-6) / 2 = 0/6 = 0.

    Solution set: n = 6, and 0.

    YOU FAIL AT LIFE

  • 11th grade-math -

    n^2= 6n
    n^2-6n=0
    n(n-6)=0
    n=0,6
