Answer 2

Answer:

(iii) p-q

(iv) a+ab

(v) 8x²y+8xy²-4x²-7y²

(vi) 4y²-3y

Step-by-step explanation:

(iii) p-(p-q)-q-(q-p)

= p-p+q-q-q+p

= p-q

(iv) 3a-2b-ab-(a-b+ab)+3ab+b-a

= 3a-a-a-2b+b+b+3ab-ab-ab

= a+ab = a(1+b)

(v) 5x²y-5x²+3yx²-3y²+x²-y²+8xy²-3y²

= 5x²y+3yx²+8xy²-5x²+x²-3y²-3y²-y²

= 8x²y+8xy²-4x²-7y²

= 8xy(x+y)-4x²-7y²

(vi) (3y²+5y-4)-(8y-y²-4)

= 3y²+5y-4-8y+y²+4

= 4y²-3y

= y(4y-3)
