A Pascal triangle is the triangular way of expanding a binomial. So the best way in expanding that function is thru Binomial Theorem and the expanded for of it is 8x^3+48x^2+98x+64
Step-by-step explanation:
Before even trying to put this into the binomial form, we must figure out the coefficients. If we go by the Pascal's Triangles way we should end up with:
1
1 1
1 2 1
1 3 3 1
Going by the last level (which is the third level) we get 3C0:1, 3C1:3, 3C2:3, 3C3:1.
Now with the equation: (a+b)^3 = 3C0a^3 + 3C1a^2 b + 3C2a b^2 + 3C3b^3 we just plug in all the values and simplify
