The statement regarding the expansion of (x + y)" that is correct is D. The coefficients of yn - 1 and yn – 1 both equal 1.
<h3>How to expand?</h3>
It should be noted that for any positive integer, n, the expression of (x + y)^n will be C(n,0)x^n + C+n, 1)x^n-1 .... C(n, n)y^n.
Here, the statement regarding the expansion of (x + y)" that is correct is that the coefficients of yn - 1 and yn – 1 is both equal to 1.

Answer:
2,2
Step-by-step explanation:
f(x)=(x-2)^2+2
=2,2
It's just one, if there isn't any other number attached to the x^2 you can just assume the leading coefficient is 1
Sin(pi/6) = 1/2
tan(pi/4) = 1
