Step-by-step explanation:

(a + b)^{3}  - (a - b)^{3}  - 6 {a}^{2} b \\ a ^{3}  + 3a ^{2} b + 3ab ^{2}  + b ^{3}  - (a ^{3}   -  3a ^{2} b + 3ab ^{2}   -  b ^{3}) - 6 {a}^{2} b \\ a ^{3}  + 3a ^{2} b + 3ab ^{2}  + b ^{3}  - a ^{3}   + 3a ^{2} b  -  3ab ^{2}    + b ^{3}) - 6 {a}^{2} b \\ 3a ^{2} b + b ^{3}  + 3a ^{2} b + b ^{3} - 6 {a}^{2} b \\ 6 {a}^{2} b + 2b ^{3}  - 6 {a}^{2} b \\ 2b ^{3}

Answer:

2b^3

Step-by-step explanation:

(a+b)^3=a^3+b^3+3ab(a+b)\\(a-b)^3=a^3-b^3-3ab(a-b)\\(a+b)^3-(a-b)^3-6a^2b\\=a^3+b^3+3ab(a+b)-[a^3-b^3-3ab(a-b)]-6a^2b\\=2b^3

Given f(x) = -x – 4, solve for x when f(x) = 6.​
Makovka662 [10]

Answer:

-10

Step-by-step explanation:

6=-x-4           plug in 6 for f(x)

10=-x             add 4 to both sides in order to cancel out the -4

-10=x             multiple each side by -1 to make the x positive
