SOLUTION OF PROBLEM: 4

Find out the quadratic equation having equal and opposite roots as that of equation (x sq -16) =0.                    ( ALG/E)

.
 Note: (x) sq stands for x square

SOLUTION: The given(x)sq-16=0 has its roots as +4 and-4. According to the given condition the required equation has its roots as equal and opposite to the given equation's roots that is the required equation will have its roots  as -4 and +4 .The required equation will therefore be (x+4)(x-4)=0 or (x)sq-16=0, which is nothing but the original equation.
