Question 1001659
What is the coefficient of the term free of x of the expansion of (2x - 5y)^4

The degree of the polynomial f(x) whose only root is 3  of multiplicity 3 is three. TRUE or False
<pre>An x doesn't exist at the term where x = {{{x^(n - n)}}}. This is at the 5th term of the expansion, or more specifically at: {{{" "[4]C[4] * (2x)^(4 - 4) * (- 5y)^4}}}.
This results in: {{{1 * (2x)^0 * (- 5y)^4}}} -------> {{{1 * 1 * 625y^4}}} -------> {{{625y^4}}}, which gives a coefficient of: {{{highlight_green(625)}}}
