A & E

Step-by-step explanation:

a = 1

b = 3

c = 5

D = b^2 - 4ac

D = 9 - 4*1*5

D = 9 -20

D = -11

x1 = $\frac{-b - \sqrt{D} }{2a}$

x2 = $\frac{-b + \sqrt{D} }{2a}$

x1 = $\frac{-3 - \sqrt{-11} }{2}$

x2 = $\frac{-3 + \sqrt{-11} }{2}$

Step-by-step explanation:

$G(t) =\displaystyle \int (4 + t + t^2)dt$

$\:\:\:\:\:\:\:=4t + \frac{1}{2}t^2 + \frac{1}{3}t^3 + C$

Check:

$\dfrac{d}{dt}(4t + \frac{1}{2}t^2 + \frac{1}{3}t^3+C)= 4 + t + t^2 =g(t)$
