Answer 1

Hey friend, ☺️ here is your answer ___________________________

2y + 1 = 0
y = - 1/2

Put this in polynomial, if the polynomial comes to zero. Then it is a multiple of 2y + 1

Lets see - -

$4 { (\frac{ - 1}{2} )}^{3} + 4 {( \frac{ - 1}{2} )}^{2} - ( \frac{ - 1}{2} ) - 1 \\ = 4 \times \frac{ - 1}{8} + 4 \times \frac{1}{4} + \frac{1}{2} - 1 \\ = \frac{ - 4}{8} + 1 + \frac{1}{2} - 1 \\ = \frac{ - 4}{8} + \frac{1}{2} \\ = \frac{ - 4 + 4}{8} \\ = \frac{0}{8} \\ = 0$

Yes, the polynomial is a factor of 2y + 1

Hope this helps you..
