Question

Select one of the factors of x2y3 − 11x2y + 6y2 − 66.

(x2y + 6)
(x2y − 6)
(y2 + 11)
(y − 3)

Answer 1

Explanation:

The factors of the equation x2y3 - 11x2y + 6y2 - 66 can be found by taking out the common terms.

x2y3 - 11x2y + 6y2 - 66

Let us take out the common from the first two terms.

⇒ x2y(y2 - 11)------>(1)

Take out common from the last two terms.

⇒ + 6 (y2 - 11)------>(2)

By combining these two, we get

x2y(y2 - 11) + 6(y2 - 11)

⇒ (x2y + 6)(y2 - 11)

Answer 2

(x^2y + 6)
