Answer:

2d(d + 3)^2(d - 3)

Step-by-step explanation:

2d^4 + 6d^3 - 18d^2 - 54d

= 2d^3(d + 3) - 18d(d + 3)

= (2d^3 - 18d)(d + 3)

= 2d (d^2 - 9)(d + 3)

= 2d(d + 3)^2(d - 3)

B) If the line is parallel, that means the slope is the same.
The slope for the original line is $\frac{-1-0}{6-2}$ = $\frac{-1}{4}$ .
The second form of coral line would be y = -1/4x + (any number). You could use y = -1/4x + 3.

c) Solve 12x = 24 + 3y for y.
3y = 12x - 24
y = 4x - 8
Perpendicular lines have negative reciprocal slopes... the negative reciprocal for -1/4 is 4. So yes, the third coral structure is perpendicular to the first coral.
