Answer 1

x2 + 6x + 8

x. 2 + 6x + 8

= 8x +8

X2 + 2x - 8

x. 2 + 2x - 8

= 4x -8

x2 + 3x + 2

x. 2 + 3x + 2

= 5x - 2

X2 + x-42

x. 2 + x - 42

= 3 x - 42

X2 + 7x + 12

x . 2 + 7x + 12

= 9x + 12

X2 + 7x + 10

x . 2 + 7x + 10

= 9x + 10

X2 + 9x-22

x . 2 + 9x - 22

= 11x - 22

m2 + 11m + 28

m . 2 + 11m + 28

= 13 m + 28

m2 - 4m + 3

m . 2 - 4 m + 3

= - 2 m  + 3

y2+ 3y + 2

y . 2 + 3y  + 2

= 5y + 2

y2 - 3y + 2

y . 2 - 3y + 2

= -y + 2

W2 + 9w + 20

w . 2 9w  + 20

= 11 w + 20

w2 - 5W - 6

w . 2 - 5w - 6

= - 3 w - 6

b2 - 4 - 5

b . 2 - 4 -5

= 2b - 9

b2 + 6b + 5

b. 2 + 6b + 5

= 8b + 5

b2 - 4b - 5

b . 2 - 4b - 5

= - 2b - 5
