Plain-text version
If a · b = M, M is different from 0 and (a + b) = 4, then (A) there are always real values for a, b (B) whenever 4 ≥ M > 0 there are real values for a, b (C) whenever 0 > M there are positive values for both a, b (D) whenever 0 > M there are negative values for both a, b
Also written as: If a * b = M, M is different from 0 and (a + b) = 4, then
