a) $-5x^{2}$ + 6x + 8

b) 6 - 7x

c) $-12x^{2}$ - 7x +4

d) 2x + 5

Step-by-step explanation:

a) (5x + 4) – (x – 2)

(5x + 4) (-x + 2)

$-5x^{2}$ + 10x - 4x + 8

$-5x^{2}$ + 6x + 8

b) (6 – 3x) + (x – 5x)

6 – 3x + x – 5x

6 - 7x

c) (4x + 5) – (3x – 2) – 6

(4x + 5) (–3x + 2) – 6

$-12x^{2}$ + 8x -15x + 10 -6

$-12x^{2}$ - 7x +4

d) 9x + 5 – 7x

2x + 5

hope this helps!
