Question

Check whether the polynomial q(t) = 4+ + 4t - t - 1 is a multiple of
2t + 1.

Answer 1

Answer:

No

Step-by-step explanation:

2t+1 = 0

t= -1/2

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