Help With PASCAls triangle please.
1.)(x-2t)^4
----------------
The 4th row is 1, 4, 6, 4, 1
--> x^4 - 4x^3*2t + 6x^2*(2t)^2 - 4x*(2t)^3 + (2t)^4
=
==================
2.)(3y+2z)^5
Row 5 is 1, 5, 10, 10, 5, 1
(3y)^5 + 5(3y)^4*2z + 10(3y)^3*(2z)^2 + 10(3y)^2*(2z)^3 + 5*3y*(2z)^4 + (2z)^5
=
----------------
Do 3 and 4 the same way.
3.)(5-2x)^5
4.)(5-2x)^5
