Question

Algebra: ( x + 1)^3

Answer 1

whats the question? expand?

Answer 2

Expand and simplify

Answer 3

= (x+1) * (x+1)^2
= (x+1) * (x^2 + 2x 1)
= x^3 + 2x^2 + x + x^2 +2x + 1
= x^3 + 3x^2 + 3x + 1

Answer 4

(x+1)(x+1)= x^2+2x+1

(x^2+2x+1)(x+1)= x^3+x^2+2x^2+2x+x+1= x^3+3x^2+3x+1

Answer 5

(x+1)(x+1)(x+1)
first do (x+1)(x+1) to get x^2+2x+1
then multiply that answer (which is equal to the first two (x+1) thingies by the third one:

(x^2 + 2x + 1)(x+1)
You get
x^3 + 3x^2 +3x + 1

Answer 6

@lalaly: Make sure to combine your like terms on the x^2 terms!
