How many real number solutions exist for 2x2 8x 8 = 0?

  • math -

    It would help if you proofread your questions before you posted them. You need to include all the signs for addition and/or subtraction. Also online "^" is used to indicate an exponent, e.g., x^2 = x squared.

    Is this your equation?

    2x^2 ± 8x ± 8 = 0

    Assuming the signs are positive,

    (2x+4)(x+2) = 0

    x = -2
