7. 8. 9. The binomial expansion of (1 + px)-3 in ascending powers of x is 1 + a x + bx2 + x3 + …, where p , a and b are constants. Find the values of p, a and b. State the range of values of x for which the expansion is valid. Write down the first 3 terms in the expansion of ( 1 – x + 2x2)-3 in ascending powers of x given that the expansion ...

The binomial expansion is based on the summation of combination statements and varying powers of your binomial terms. (be careful with negative signs) Hint #1: Powers of each summation term will add to equal power of binomial expression (n) Hint #2: Combinations will always be paired with the power of the second term from the binomial (b) Hint #3:
