Factorise : x^2y^2 - 3xy - 40

x 2 y 2 \- 3xy \- 40 = x 2 y 2 \- (8 \- 5)xy \- 40 = x 2 y 2 \- 8xy \+ 5xy \- 40 = (x 2 y 2 \- 8xy) \+ (5xy \- 40) = xy(xy \- 8) \+ 5(xy \- 8) = (xy \- 8)(xy \+ 5) Hence, x 2 y 2 \- 3xy \- 40 = (xy \- 8)(xy \+ 5)

Answer

x²y² - 3xy - 40

= x²y² - (8 - 5)xy - 40

= x²y² - 8xy + 5xy - 40

= (x²y² - 8xy) + (5xy - 40)

= xy(xy - 8) + 5(xy - 8)

= (xy - 8)(xy + 5)

Hence, x²y² - 3xy - 40 = (xy - 8)(xy + 5)
