Answer 1

Answer:

Question 2:

Subtract the second expression from the first:

(i) 5x2 - 6xy + 2; 3x2 + 10xy -8

(ii) m2n - 8 + mn2; 7 - m2n - mn2

(iii) 5x2 + 4y2 - 6y + 8; x2 - 5y2 + 2xy + 3y - 10

ANSWER:

(i) 5x2 - 6xy + 2 3x2 + 10xy - 8 - - + 2x2 - 16xy +10

(ii) m2n - 8 + mn2 -m2n + 7 -mn2 + - + 2m2n - 15 + 2mn2

(iii) 5x2 + 4y2 - 6y + 8 x2 - 5y2 + 2xy
