(c) –4x2y – y3 from x3 + 3xy2 – x2y.
(d) x4 + 3x3y3 + 5y4 from 2x4 – x3y3 + 7y4.
(e) ab – bc – ca from – ab + bc + ca.
(f) –2a2 – 2b2 from – a2 – b2 + 2ab.
(g) x3y2 + 3x2y2 – 7xy3 from x4 + y4 + 3x2y2 – xy3.
(h) 2(ab + bc + ca) from –ab – bc – ca.
(i) 4.5x5 –3.4x2+5.7 from 5x4–3.2x2–7.3x.
(j) 11 – 15y2 from y3 – 15y2 – y – 11.
(a) – 3p2qr – (–7p2qr)
– 3p2qr + 7p2qr
4p2qr
(b) b2 + ab – (–a2 – ab)
b2 + ab + a2 + ab
b2 + 2ab + a2
(c) x3 + 3xy2 – x2y – (–4x2y – y3)
x3 + 3xy2 – x2y + 4x2y + y3
x3 + 3xy2 + 3x2y + y3
(d) 2x4 – x3y3 + 7y4 – (x4 + 3x3y3 + 5y4)
2x4 – x3y3 + 7y4 – x4 - 3x3y3 - 5y4
x4 – 4x3y3 + 2y4
(e) – ab + bc + ca – (ab – bc – ca)
–2ab + 2bc + 2ca
(f) – a2 – b2 + 2ab – (–2a2 – 2b2)
– a2 – b2 + 2ab + 2a2 + 2b2
a2 + b2 + 2ab
(g) x4 + y4 + 3x2y2 – xy3 – (x3y2 + 3x2y2 – 7xy3)
x4 + y4 + 3x2y2 – xy3 – x3y2 - 3x2y2 + 7xy3
x4 + y4 - x3y3 + 6xy3
(h) –ab – bc – ca – (2(ab + bc + ca))
-3ab – 3bc – 3ca
(i) 5x4–3.2x2–7.3x – (4.5x5 –3.4x2+5.7)
5x4–3.2x2–7.3x – 4.5x5 + 3.4x2 - 5.7
– 4.5x5 + 5x4 + 0.2x2 – 7.3x – 5.7
(j) y3 – 15y2 – y – 11 – (11 – 15y2)
y3 – 15y2 – y – 11 – 11 + 15y2
y3 – y – 22
