Convert each of the following argu- ments into formal statements, e.g., define sentences existentially and/or universally quantified statements. Then determine which rules of logic have been applied and explain whether or not they have been ap- plied correctly. 8. All numbers that are divisible bytwo are even. 17 is not divisible bytwo. Therefore 17 is not even.9. If b2 > 4ac then there are two real0 thatare given by (-b±vb? – 4ac)/(2a).Therefore x? + 5x + 1 = 0 has tworoots of ax2 + bx + c =real roots.10. If a is any real number then x2 +a?0 does not have any real so-lution. Therefore there is no realsolution to x2 + 4 = 0.
