Expand using pascal’s triangle (3m-2n)^5
1 answer:
Check the picture below.
recall that, the first term starst off with the highest exponent, and wanes down to 0 on every term, whilst the second term starts off with 0, and waxes up to the highest on every term.
so the pascal triangle provides the coefficients for every term in the expansion, and from there just expand each one.
