Answer:
-4x+3x power of 2 +2
Step-by-step explanation:
3x² - 4x + 2
distribute -2 into (3x - 1) and distribute x into (3x + 2)
=> -6x + 2 + 3x² + 2x
combine like terms
=> 3x² - 4x + 2
3x-22=80+x
3x-x=80+22
2x=102
x=51
the exterior angle is (3x-22) and then is equal to sum of 80 and x
and then we get 51
