1.
You wrote this in an ambiguous way. Is it (14/7)*x or 14/(7x)? Use parentheses next time.
2.
t = 0
t = -12
are the two solutions.
3.
2*a*b - 2
4.
c = 2
c = -4
are the two solutions.
5.
11*x^2 + 2*x - 29

#1 is already simplified (7 doesn't go into everything and there is no x in all the numbers divided by 7x + 2)
#2 _ t = 2(square root of)-3t
#3 is 2ab -2
#4 is (c+4)(c-2)
#5 is 11x^2 + 2x -29
