Question

Tough one!
Solve the equation for x.
a2x2 + 14ax + 49 = 0 (a ≠ 0)
What is the:
x = _____ (smaller value)
x = _____ (larger value)

Answer 1

a= +/- 7

Answer 2

you sure?

Answer 3

if by a2x2 you mean a^2 yes.

Answer 4

x=-7/a
only one solution

Answer 5

oh woops i see the problem ok hang on...
(ax+7)^2=0
so -7/a is right.

Answer 6

(ax+7)^2=0
ax+7=0
ax=-7
x=-7/a
a does not equal 0

Answer 7

as a gets closer to 0 from the right, you are geting closer to the smallest possible value for a but you will never reach the smallest value since -7/a has vertical asymptote at a=0
now the greates possible value will also never be reach because of a=0
