Question 96440: Formulas: (a+b)^2= a^2+2ab+b^2
(a+b)^3= a^3+3a^2b+3ab^2+b^3
(a+b)^4= a^4+4a^3b+6a^2b^2+4ab^3+b^4
(a+b)^5= a^5+5a^4b^1+a^3b^2+10a^2b^3+5a^1b^4+b^5
How would I solve?
1. (4+x)^3
2. (3x+4)^3
3. (2+2)^5
4. (3x+5)^4

You can put this solution on YOUR website!
4+x
4+x multiply
------------------
16+4x+4x+x^2 combine like terms
16+8x+x^2
4+x multiply
--------------------------
64+32x+4x^2+16x+8x^2+x^3 combine like terms
64+48x+12x^2+x^3
---------------------------------------
I solved the first now you tackle the rest.
