Factor by grouping. Step by step appreciated

(x^2+8) ( y+4)

Step-by-step explanation:

x^2y + 8y+ 4x^2 +32

Splitting into two groups

x^2y + 8y+      4x^2 +32

Factor y out of the first group  and 4 out of the second group

y( x^2+8)    + 4(x^2+8)

Factor out (x^2+8)

(x^2+8) ( y+4)

2x3 – 6x2 – 14x + 24 square centimeters

if i'm wrong i'm sorry : )

(f - g)(x) = 5x^3 - 3

step-by-step explanation:

rearrange these functions vertically, with like terms in separate columns:

f(x) = 5x^3 - 2

g(x) =         +1

now subtract, column by column:

(f - g)(x) = 5x^3 - 3
