The following graph shows a decrease in aggregate demand (AD) in a hypothetical country. Specifically, aggregate demand shifts to the left from AD1 AD 1 to AD2 AD 2 , causing the quantity of output demanded to fall at all price levels. For example, at a price level of 140, output is now $200 billion, where previously it was $300 billion.

answer: standard form is ax^2 + bx + c = 0

step-by-step explanation:

standard form is ax^2 + bx + c = 0

(2x + 1)(x - 2) = 0

distribute to get into standard form

2x^2 - 4x + x - 2 = 0

2x^2 - 3x - 2 = 0

a = 2, b= -3, c = -2

a is your answer

the equivalent expression are always the hardest ones but you look at the gcf also
