8) (-c+b/4) ^2

1) = (2-a) ²=4-4a+a²

2) = (- (b+3)) ² = (b+3) ²=b²+6b+9

3) = (4-n) ²=16-8n+n²

4) = (- (x+10)) ² = (x+10) ² = x²+20x+100

5) = (- (2x+3y)) ² = (2x+3y) ² = 4x² + 12xy+9y²

6) = (1/2b - 1/3a) ² = 1/4 b² - 1/3 ab + 1/9 a²

7) = (- (1.3x+6)) ² = (1.3x+6) ² = 1.69x²+15.6x+36

8) = (b/4 - c) ² = b²/16 - 1/2 bc + c²
