Answer:
Please look at the picture above for the solution.
To find the first four terms of the given, expand it first using the Binomial Theorem.
Substitute the values to the formula then simplify. You can use a calculator to simplify the exponents and the factorial notation.
The expanded form is:
[tex] {x}^{9} - 45 {x}^{8} + 900 {x}^{7} - 10500 {x}^{6} + 78750 {x}^{5} - 393750 {x}^{4} + 1312500 {x}^{3} - 2812500 {x}^{2} + 3515625x - 1953125[/tex]
Therefore, the first four terms are:
[tex] {x}^{9} [/tex]
[tex] - 45 {x}^{8} [/tex]
[tex]900 {x}^{7} [/tex]
[tex] - 10500 {x}^{6} [/tex]
