<PRE><B>Question 989747</B>
.
Let me re-formulate your question in this form:


Solve the system of two equations


{{{system (y =  -2x^2 + 12x + 2,
y = x^2 -1)}}}.


Is this correct re-formulation?
-------------------------------------------------------


If so, &amp;nbsp;then the right sides of these equations are the same &amp;nbsp;(because left sides are identical), &amp;nbsp;and you can write


{{{x^2 -1}}} = {{{-2x^2 + 12x + 2}}}. 


It is a quadratic equation. 


Can you solve it?
