The square of (2a + b) - 8ab factorization factor; a, B are any real numbers, the total value of the quadratic power of a + the quadratic power of b-2a-4b + 8 is : A. negative B. positive c.0 D. non negative

The square of (2a + b) - 8ab factorization factor; a, B are any real numbers, the total value of the quadratic power of a + the quadratic power of b-2a-4b + 8 is : A. negative B. positive c.0 D. non negative

The square of (2a-b)
Positive number because the original problem can be rewritten as (A-1) square + (b-2) square + 3, so positive number
