(i) [x + 2y] and [2x - 9y + 7]

Answer 1

Step-by-step explanation:

[x + 2y][2x - 9y + 7]

x [2x - 9y + 7] + 2y [2x - 9y + 7]

(2xsquare - 9xy + 7x) + (4xy - 18ysquare + 14y)

2xsquare + 7x - 9xy + 4xy - 18ysquare + 14y

2xsquare + 7x - 5xy - 18ysquare + 14y

Hope its help you

Answer 2

Answer:

2x^2 - 9xy + 7x + 4xy -18y^2 + 14

= 2x^2 - 18xy + 5xy + 14
