Step-by-step explanation:

(6−)(5−4)(+2)

(6-x)(5-4x)(x+2)(6−x)(5−4x)(x+2)

Simplify

1

Rearrange terms

(6−)(5−4)(+2)

({\color{#c92786}{6-x}})(5-4x)(x+2)(6−x)(5−4x)(x+2)

(−+6)(5−4)(+2)

({\color{#c92786}{-x+6}})(5-4x)(x+2)(−x+6)(5−4x)(x+2)

2

Rearrange terms

(−+6)(5−4)(+2)

(-x+6)({\color{#c92786}{5-4x}})(x+2)(−x+6)(5−4x)(x+2)

(−+6)(−4+5)(+2)

(-x+6)({\color{#c92786}{-4x+5}})(x+2)(−x+6)(−4x+5)(x+2)

Distribute

4

Re-order terms so that constants are on the left

(−4+5)(+2)(−)+6(−4+5)(+2)

(-4x+5)(x+2)\left(-x\right)+6(-4x+5)(x+2)(−4x+5)(x+2)(−x)+6(−4x+5)(x+2)

−(−4+5)(+2)⋅+6(−4+5)(+2)

-(-4x+5)(x+2) \cdot x+6(-4x+5)(x+2)−(−4x+5)(x+2)⋅x+6(−4x+5)(x+2)

5

Distribute

−(−4+5)(+2)⋅+6(−4+5)(+2)

-{\color{#c92786}{(-4x+5)(x+2) \cdot x}}+6(-4x+5)(x+2)−(−4x+5)(x+2)⋅x+6(−4x+5)(x+2)

−(−4(+2)⋅2+5(+2))+6(−4+5)(+2)

-\left({\color{#c92786}{-4(x+2) \cdot x^{2}+5x(x+2)}}\right)+6(-4x+5)(x+2)−(−4(x+2)⋅x2+5x(x+2))+6(−4x+5)(x+2)

6

Distribute

−(−4(+2)⋅2+5(+2))+6(−4+5)(+2)

-\left({\color{#c92786}{-4(x+2) \cdot x^{2}}}+5x(x+2)\right)+6(-4x+5)(x+2)−(−4(x+2)⋅x2+5x(x+2))+6(−4x+5)(x+2)

−(−43−82+5(+2))+6(−4+5)(+2)

-\left({\color{#c92786}{-4x^{3}-8x^{2}}}+5x(x+2)\right)+6(-4x+5)(x+2)−(−4x3−8x2+5x(x+2))+6(−4x+5)(x+2)

7

Distribute

−(−43−82+5(+2))+6(−4+5)(+2)

-\left(-4x^{3}-8x^{2}+{\color{#c92786}{5x(x+2)}}\right)+6(-4x+5)(x+2)−(−4x3−8x2+5x(x+2))+6(−4x+5)(x+2)

−(−43−82+52+10)+6(−4+5)(+2)

-\left(-4x^{3}-8x^{2}+{\color{#c92786}{5x^{2}+10x}}\right)+6(-4x+5)(x+2)−(
