a. (f+g)(x)= 2x^2-3x+1+6x^2+9x+4= 8x^2+6x+5
b. (f+g)(2)= 8 * 2^2 + 6 * 2 +5 = 49
c. (f-g)(x)= 2x^2-3x+1-6x^2+9x+4= -4x^2-9x-3
d. (f-g)(-3)= -4 * (-3)^2 - 9 * (-3) - 3= -12
Hope it helps!

The question let's us set up the equation 160= 16t^2+96t+16 and we just solve for t to get t= 3(sqrt 2 - 1) and -3(sqrt 2 - 1).
