A number x is multiplied with itself and then added to the product of 4 and x. If the result of these two operations is 5, what is the value of x?	Choose the most appropriate option:
A) -4
B) -2
C) 2
D) 1 and -5
E) Cannot be determined.
A number x is multiplied with itself --&gt; X^2   added to the product of 4 and x --&gt; X^2+4X   If the result of these two operations is -4 --&gt; X^2+4X=5   i.e X^2+4X-5=0 is the Quadratic equation which needs to be solved.   (X-1)(X+5) = 0   Hence X=1. C=-5   IMO 1 and -5
