Answer:
2a
Step-by-step explanation:
2a(8+9b)
Open the bracket you have
16a+18ab
X = Negative 2 (-2)
x^2+20=2x move 2x to the left
x^2-2x+20=0
Quadratic formula =
x=1± i√19
divide 50 by 6.2, because 6.2 and x are entangled by multiplication. once you do that, you will have your answer. it should be 8.06
