    Separate 27 into two parts whose product is 92.

    This is to find two numbers such that the sum is 27 and the product is 92.

    Let \(x + y = 27 \), such that \(xy = 92 \)

    \(x = 27 - y\)

    \( (27 - y) y = 92\)

    \(27y - y^2 = 92\)

    \(y^2 -27y + 92 = 0\)

    \( (y - 23)(y - 4 ) = 0\)

    \( y_1 = 4\) and \( y_2 = 23\)

    \(x + 4 = 27 \)

    \(x = 27 - 4 = 23 \)

    The numbers are 23 and 4.
