Answer:
Step-by-step explanation:
Left Panel
3 || 1 - 7 13 - 3
3 -12 3
==================
1 - 4 1 0
q(x) = x^2 - 4x + 1
r(x) = 0
b(x) = x - 3
Right Panel
The very first step should be (d - vt) = - 1/2 a t^2 but I don't see that there. The second from the bottom is close but it is not right. What is there is multiplying through by -1
vt - d = 1/2 a t^2 The second step is to multiply both sides by 2
2(vt - d) = at^2 The third step is divide both sides by t^2
2(vt - d)/t^2 = a
