Simplify:(i) (a +b + c)2 + (a − b + c)2(ii) (a +b + c)2 − (a − b

1.	Simplify:(i) (a +b + c)2 + (a − b + c)2(ii) (a +b + c)2 − (a − b + c)2(iii) (a +b + c)2 + (a − b + c)2 + (a +b − c)2(iv) (2x + p − c)2 − (2x − p + c)2(v) (x2 + y2 − z2) − (x2 − y2 + z2)2
Answer» Simplify: (i) (a +b + c)² + (a − b + c)² (ii) (a +b + c)² − (a − b + c)2 (iii) (a +b + c)²+ (a − b + c)² + (a +b − c)² (iv) (2x + p − c)²− (2x − p + c)² (v) (x² + y²− z²) − (x² − y² + z²)²
