Factor the following polynomials by recognizing the coefficients.
1.x^2 + 2 xy+y^2
2.x^3 + 3 x^2 + 3 x+ 1
3.x^5 + 5 x^4 + 10 x^3 + 10 x^2 + 5 x+ 1
- 27x^3 − 27 x^2 + 9 x− 1
5.x^3 + 12 x^2 + 48 x+ 64
Expand the following binomials using Pascal’s Triangle.
6.( 2 x− 3 )^3
7.( 3 x+ 4 )^4
8.(x−y)^7
9.(a+b)^10
10.( 2 x+ 5 )^5
11.( 4 x− 1 )^4
12.( 5 x+ 2 )^3
13.(x+y)^6
14.( 3 x+ 2 y)^3
15.( 5 x− 2 y)^4
