    x^2(4+(1/x)-(1/x^2))=0 gets rid of the denom

    the real solution to any equation, like above with a degree of two it will be quadratic that means that the real solution is any point in which that equation crosses the x-axis or in other words the x-intercepts the term real refers to any solution that can be graphed on a real plane not including imaginary terms or number

    or if you are finding a solution to a pair of equations the solution represents the point where the two equations intersect

    you haven'y given me any context clues that you are trying to solve two equations intersectio point, that means it will be the x-intercepts

    almost, we have to rationalize the denomintator, because this equation represents a function and only real solutions which can't have a denom. of zero therefore we must get rid of the variables in the denom.

    mulitply the entire equation on both sides by the largest variable in the denom.
