2. Add the following algebraic expressions.

a. 3x, 5x, (-9x) and 2x

b. xy2 + 3x + 5, 4xy2 + (-8x)

c. 9x2 – xy + 8y2, (-4x2) + 3xy – 2y2 and 5x2 + 2xy +7y2

Ans:

a. = 3x + 5x + (-9x) + 2x

= 10x + (-9x)

= 10x – 9x

= x

b. = [xy2 + 3x + 5] + [4xy2 + (-8x)]

= [xy2 + 3x + 5] + [4xy2 – 8x]

= xy2 + 3x +5 + 4xy2 – 8x

= xy2 + 4xy2 + 3x – 8x + 5

= 5xy2 – 5x + 5
