You cannot since it has no solution.
The answer is x = 2.

y = x2 + 14x + 21; a = 1, b = 14, c = 21 x-coordinate = -b/2a = -14/2 = -7 if it is y = x2 + 14 + 21, the x-coordinate is zero, since b = 0.
x/11 + 21 = 7 x/11 = -14 x = -154
X+14=-21 X=-21-14 X=-35 is your answer.
You cannot since it has no solution.
1) x=21 2) x=14.45
The answer is x = 2.
why will the equations x+14=37 and x-14=37 have different solutions for x
If you mean: x squared+9x+14 = 0 then by using the quadratic equation formula x = -2 or x = -7
x = 6
x+3=14 x+3-3 = 14-3 (subtract 3 from both sides to solve for x) x = 11

y = x2 + 14x + 21; a = 1, b = 14, c = 21 x-coordinate = -b/2a = -14/2 = -7 if it is y = x2 + 14 + 21, the x-coordinate is zero, since b = 0.
22+2x = 37+6+x 2x-x = 37+6-22 x = 21
