Question

check polynomial q(t) = 4t + 4t² - t - 1 is a multiple of 2t+1​

Answer 1

Answer:

No

Step-by-step explanation:

q(t) = 4t + 4t² - t - 1

2t+1 = 0

2t = -1

t= -1/2

If q(t) is multiple of 2t+1 ,

then q(-1/2) must equal to zero.

q(-1/2)=4 (-1/2)+4(-1/2)²-1/2-1

= -2+1-0.5-1

=-2.5

So it is not multiple of q(t).
