Write the binomial expansion of (t-3)^5

Step-by-step explanation:

(t-3)^5 is the same as (t + (-3))^5

First:  t starts at the highest power and goes down and (-3) starts at the lowest power and goes up

Second: from the Pascal triangles take the coefficients  1  5  10  10  5  1

Anything to power 0 is equal to 1

Negative number to an odd power is negative, to a even power is positive
