(t+4)(t+5)
(t-1)(t-2)(t+5)(t-8)=-360
$$\prod_{n=1}^{13}\left(1-\frac{4}{(2n-1)^2}\right)=?$$
$$\prod_{n=1}^{25}\left(1-\frac{4}{n^2}\right)=?$$
CALCULATE
x+3 % $x^{2}$-9
if the conjucate of 2a+ib is (aa+b)-(a+2b) then find the value of a and b
give the answer please
the answer is not 0
x+3 / $x^{2}$-9
$$\prod_{n=1}^{25}\left(1-\frac{4}{n^2}\right)$$
