Question

factorise the following expressions​

Answer 1

AnSwer:

(i) x²y² - 7xy + 10

★ By splitting the middle term:

→ x²y² - 2xy - 5xy + 10

→ xy(xy - 2) - 5(xy - 2)

→ (xy - 5)(xy - 2)

(ii) 21x² - 13xy + 2y²

★ By splitting middle term and factoring first term:

→ (3)(7)x² - 6xy - 7xy + 2y²

→ 3x( 7x - 2y) - y(7x - 2y)

→ (7x - 2y)(3x - y)
