Substituting x = 3 in the equation gives:


9 + 3a + b = 0


Then substituting x = -4 into the equation gives:


16 - 4a + b = 0


Subtracting the first equation from the second gives:


(16 - 9) + (-4a - 3a) + (b - b) = 0


7 - 7a = 0


7a = 7


a = 1


Substituting a = 1 into 9 + 3a + b = 0 then gives:


9 + 3(1) + b = 0


12 + b = 0


b = -12


Solution: a = 1, b = -12
