$solve \: questions \: by \: showing \: the \: full \: method \: or \: i \: will \: not \: mark \: you \: as \: a \: brainliest$

Q.1 Subtract

(a) -3x²-4x-2 from x²-3x+7

(b) 5y-x+3z from x-3y

(c) 3ab+2a-3b from

Q.3 Simplify the following

1. 5ab-7b²c - 6ab + 2bc²-4b² c-3bc²

2. m²-2n²+7mn-5m²-11mn-3n²+2n²​

Answer 1

a) x² - 3x + 7 - (-3x² - 4x - 2)

x² - 3x + 7 + 3x² + 4x + 2

4x² + x + 9

b)x - 3y - (5y - x + 3z)

x - 3y - 5y + x - 3z

2x - 8y - 3z

c)3ab + 2a - 3b

1. 5ab-7b²c - 6ab + 2bc²-4b² c-3bc²

2. m²-2n²+7mn-5m²-11mn-3n²+2n²

Answer 2

In Q-1 (c) you have not written the full answer so i emwas unable to answer that. Hope you have understood the rest questions. Thank you
