Question

HOW DO I SOLVE THIS?
Use the binomial theorem to expand
(d-4b)^3

Answer 1

you have to apply pascals' triangle

Answer 2

the binomial's term is 3 so you have to look at the pattern 1-3-3-1 and apply it to the equation with the d term starting at the 3rd power and the b power starting at the 1st power and decrease the d term by 1 while increasing the b term by 1

Answer 3

d^3-4b + d^2 -4 * 3 b^2 .......

Answer 4

keeps going until the end of the pattern

Answer 5

okay thank you!
