Answer 1

Hey mate!!!

Here's your answer!!!

${( a - 2b + 3c)}^{2} - {( a + 2b - 3c)}^{2} \\ As \: we \: know, \\ {x}^{2} - {y}^{2} = (x + y)(x - y) \\ ATQ \\ = > ( a - 2b + 3 c- (a + 2b - 3c)(a - 2b + 3c + (a + 2b - 3c) \\ = > ( a - 2b + 3c - a - 2b + 3c)(a - 2b + 3c + a + 2b - 3c) \\ = > ( - 4b + 6c)(2a) \\ = > (2)( - 2b + 3c)(2a) \\ = > 4a( - 2b + 3c) Ans.$
