You can combine the -6 and -1 to -7. So the expression can be simplified as -3x-7
-4.9t²+7.5t+1.8=2.1
-4.9t²+7.5t-0.3=0
t=-7.5±√(56.25-4*-4.9*-.3)/-2*4.9
t=-7.5±√(44.49/-9.8
t=(-7.5±6.67)/-9.8
t=-.83/-9.8 = .085 or t= -14.17/-9.8 = 1.446
Value of the CD after 3 months is given by 300(1 + 0.03 / 4) = 300(1 + 0.0075) = 300 x 1.0075 = $302.25.
Therefore, interest for 3 months = $302.25 - $300 = $2.25
