= (10 – 3)m^{2} + (-9 + 7 – 5) m – 8

= 7m^{2} + (-7m) – 8

= 7m^{2} – 7m – 8

iv) 9x^{2} – 6 + 4x + 11- 6x^{2} – 2x + 3x^{2} – 2

= (9x^{2}-6x^{2} + 3x^{2}) + (4x-2x) + (-6 + 11 -2)

Question 1.

Answer the following expressions (Page No. 206)

i) x – 2y, 3x + 4y

ii) 4m^{2} – 7n^{2} + 5 mil, 3m^{2} + 5n^{2} – 2mn

iii) 3a – 4b, 5c – 7a + 2b

Solution:

i) x – 2y, 3x + 4y = (x – 2y) + (3x + 4y)

= (x + 3x) + (-2y + 4y) = 4x + 2y

ii) 4m^{2} – 7n^{2} + 5mn, 3m^{2} + 5n^{2} – 2mn = (4m^{2} – 7n^{2} + 5mn) + (3m^{2} + 5n^{2} – 2mn)

= (4m^{2} + 3m^{2}) + (-7n^{2} + 5n^{2}) + (5mn – 2mn)

= 7 m^{2} + (-2n^{2}) + 3mn = 7 m^{2} – 2n^{2} + 3mn

iii) 3a – 4b, 5c – 7a + 2b = (3a – 4b) + (5c – 7a + 2b) = (3a – 7a) + (-4b + 2b) + 5c = -4a – 2b + 5c
