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 0, what is the value of x?
Answers.
A) -4 and 0	B) -2	C) 2	D) 4	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 0 --&gt; X^2+4X=0   i.e X^2+4X=0 is the Quadratic equation which needs to be solved.   X(X+4) = 0   Hence X=0. X=-4   IMO -4 and 0
