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