Answer 1

5.
`6x^2 - x - 2`

6.
`9x^2 - 15x + 6(1)/(4)`

Explanation:

5:

• 
  `(x+ (1)/(2)) (6x-4)`
• 
  `(x)(6x) + (x)(-4) + ((1)/(2))(6x)+((1)/(2))(-4)`
• 
  `6x^2 - 4x + 3x - 2`
• 
  `6x^2 - x - 2`

6:

• 
  `(3x-(5)/(2))^2`
• 
  `(3x - (5)/(2))(3x - (5)/(2))`
• 
  `(3x)(3x) + (3x)((-5)/(2)) + ((-5)/(2))(3x) + ((-5)/(2))((-5)/(2))`
• 
  `9x^2 - (15)/(2)x - (15)/(2)x + (25)/(4)`
• 
  `9x^2 - 15x + (25)/(4)`
• 
  `9x^2 - 15x + 6(1)/(4)`
