(3. The polynomial function \( B ( x ) = x ^ { 3 } - 21 x + 20 \) has a known factor of \( ( x - 4 ) \) . Use long division or the rectangle diagram to find the other factor.
(4.Finish factoring \( B ( x ) \) and rewrite it as a product of linear factors (factored form with \( 3 \) factors).
.
3. x\(^{2}\)+4x-5
4. B(x)=(x-4)(x-1)(x+5)
Given the general term of the sequence, determine the first \(5\) terms:
\(a ( n ) = ( n - 1 ) / ( n + 1 )\) *
