For what values of a does the equation ax +a^2=0
have exactly one solution in the interval (−1, 2)?
ax + a^2 = 0
a(x + a) = 0
a = 0 x + a = 0
a = 0 x = -a
reject accept
This will have exactly one solution when a = (-2.0) U (0, 1)
followup questions:
have a solution in the interval (−1, 2)?
perform for all x from the interval (−1, 2)?
