7=

$[tex]24 {x}^{2} + 72x + 54 \\ 6(4 {x}^{2} + 12x + 9) \\ = 6(2x + 3) {}^{2}$[/tex]

8=

$[tex] {x}^{2} - 11x + 30 \\ {x}^{2} - 5x - 6x + 30 \\ = (x - 6)(x - 5)$[/tex]

9=

$[tex]6 {x}^{2} + 40x - 14 \\ 2(3 {x}^{2} + 20x - 7) \\ = 2(3x - 1)(x + 7)$[/tex]

10=

$[tex]56 {x}^{2} - 24x - 32 \\ 8(7 {x}^{2} - 3x - 4) \\ = 8(x - 1)(7x - 4)$[/tex]

11=

$[tex]32 {x}^{2} - 52x + 6 \\ 2(16 {x}^{2} - 26x + 3) \\ = 2(2x - 3)(8x - 1)$[/tex]

12=

$[tex]16 {x}^{2} - 32x + 15 \\ 16 {x}^{2} - 12x - 20x + 15 \\ = (4x - 5)(4x - 3)$[/tex]

13=

$[tex]35 {x}^{2} + 33x + 4 \\ 35 {x}^{2} + 28x + 5x + 4 \\ = (7x + 1)(5x + 4)$[/tex]

14=

$[tex]15 {x}^{2} - 26x + 8 \\ 15 {x}^{2} - 6x - 20x + 8 \\ = (3x - 4)(5x - 2)$[/tex]

15=

$[tex]18 {x}^{2} + 39x - 24 \\ 3(6x + 13x - 8) \\ = 3(2x - 1)(3x + 8)$[/tex]

16=

$[tex]8 {x}^{2} - 32 \\ 8( {x}^{2} - 4) \\ = 8(x - 2)(x + 2)$[/tex]
