Answer:

\boxed{  \bold{\sf{ { \boxed{ \sf{8 {x}^{5}  + 4 {x}^{4}  - 12 {x}^{2} }}}}}}

Option C is the correct option.

Step-by-step explanation:

\sf{4 {x}^{2} (2 {x}^{3}  +  {x}^{2}  - 3})

Distribute 4x through the parentheses.

\dashrightarrow{ \sf{4 {x}^{2}   \times \: 2 {x}^{3}  + 4 {x}^{2}   \times  {x}^{2}    - 4 {x}^{2}   \times 3}}

\dashrightarrow{ \sf{8 {x}^{5}  + 4 {x}^{4}  - 12 {x}^{2} }}

Hope I helped!

Best regards! :D

What is the equation of the line that passes through the point (- 1, 5) and is parallel to the line y = - 3x + 5
Harlamova29_29 [7]

Answer:

<h2>          y - 5 = -3(x + 1)</h2>

Step-by-step explanation:

Parallel lines has the same slope.

The equation of a line that passing through point (x₁, y₁) with a slope of m is:

y - y₁ = m(x - x₁)

m = -3

(-1, 5)   ⇒  x₁ = -1,  y₁ = 5

Therefore the equation:

y - 5 = -3(x + 1)
