Decide whether the statement is true or false. If it is false, tell why.If k is a positive number, then the equation -x2 = -144k has no real solutions.

A. False; the equation is equivalent to x2 = 144k, where x2 and 144k are positive, so it will have two real solutions B. False; the equation is equivalent to x2 = 144k, where x2 and 144k are positive, so the equation will have one real number solution C. True
