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 12, what is the value of x?  Choose the correct choice from the following answers: A) -4 B) -2 C) 2 and 6 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 -4 --&gt; X^2+4X=4   i.e X^2+4X-12=0 is the Quadratic equation which needs to be solved.   (X-2)(X+6) = 0   Hence X=2, X=-6   IMO 2 and 6
