1. Simplify by removing brackets :
(a) 5a + a? - [3a? - (1 - 2a - a)- 3a"] +1
(b) 2c - [3a - {c - (25 - 3a) + 4b - 3(c-a-2b)}]
(c) x- [x2 - {x?- (x2 - 2) - 2z2} +2?1
(d) 2(a + b2 + 2ab) - [2(a² + b2 - 2ab) - {-b9 + 4(a-3)}]
(e) [2 - 3x + 5y - (x - 2y)] - [4x - (2x - 2x + 3y)]
(f) -a(b + c - a)-(-a(2a + b -c) - 4a(b + c)]
(g) 3x²y - 2xy 2 - xy - [xy(x - 2y) - xy{y - 2x - 2}]
(h) -(x2 + y2 - Z) - [3x? +(2y2 - x) - x2 - y2 - 2]​
