Pre Calc - Lesson 8 - Pascal's Triangle

4) Expand the binomial using Pascal's Triangle for the coefficients. Simplify. (x+4)^4

(x+4)^4=x^4+16x^3+96x^2+256x+256

2) Expand the binomial using Pascal's Triangle for the coefficients. Simplify. (x+a)^2

(x+a)^2=x^2+2xa+a^2

3) Expand the binomial using Pascal's Triangle for the coefficients. Simplify. (x-3)^3

(x-3)^3=x^3-9x^2+27x-27

5) Expand the binomial using Pascal's Triangle for the coefficients. Simplify. (x-4)^4

(x-4)^4=x^4-16x^3+96x^2-256x+256

1) Choose the correct numbers on the blanks in the Pascal's Triangle. 1 1 1 1 2 1 1 check 3 1 1 4 6 4 1 1 check 10 10 5 1 1 6 15 20 15 6 1 1 7 21 35 35 check 7 1

The first check (on the top) is 3. The second check (near the middle to the left) is 5. The third check (on the bottom) is 21.
