[ "A)16", "B)8", "C)2", "D)-4" ]
D
Explanatory Answer Any quadratic equation of the form ax2 + bx + c = 0 will have real and equal roots if its discriminant b2 - 4ac = 0. In the given equation x2 - mx + 4 = 0, a = 1, b = -m and c = 4. Therefore, b2 - 4ac = m2 - 4(4)(1) = m2 - 16. The roots of the given equation are real and equal. Therefore, m2 - 16 = 0...
