Correct Answer: Option C

Explanation

\(x^{2} + x^{2}y + 3x - 10y + 3xy -10\)

= \(x^{2} + x^{2}y + 3x + 3xy - 10y - 10  = x^{2}(1 + y) + 3x(1 + y) - 10(y + 1)\)

= \((x^{2} + 3x - 10)(y + 1)\)

= \((x^{2} + 3x - 10) = x^{2} - 2x + 5x - 10\)

= \(x(x - 2) + 5(x - 2) = (x - 2)(x +5)\)

\(\therefore x^{2} + x^{2}y + 3x - 10y + 3xy -10 = (x - 2)(x + 5)(y + 1)\).
