Remainder theorem exercises,
Polynomial f (x) divided by x ^ 2; + 2x + 3 co x + 12, f (x) divided by (x + 1) ^ 2 co 5x + 4, find the remainder of polynomial f (x) divided by (x + 1) (x ^ 2; + 2x + 3)
I don't know the remainder theorem

It is known from the first condition that there exists a polynomial P (x) such that f (x) = (x ^ 2 + 2x + 3) * P (x) + X + 12; (1)
From the second condition, we know that there exists a polynomial Q (x) such that f (x) = (x + 1) ^ 2 * q (x) + 5x + 4. (2)
(2) Where, let x = -- 1 get f (- - 1) = 0 * q (- - 1) + 5 * (-- 1) + 4 = -- 1, and substitute (1) to get f (- - 1)
--1 = (1 -- 2 + 3) * P (- - 1) -- 1 + 12, then p (- - 1) = -- 6
So let P (x) = (x + 1) * r (x) - 6, where R (x) is a polynomial
f(x)=(x^2+2x+3)*(x+1)*r(x)--6(x^2+2x+3)+x+12=(x+1)(x^2+2x+3)*r(x)--(6x^2-+11x+6) （3）
From (3), we know that the remainder of F (x) divided by (x + 1) (x ^ 2 + 2x + 3) is -- (6x ^ 2 - + 11x + 6)

Macroeconomic issues,
Given that the GDP is 2 billion US dollars, the government budget has a deficit of 200 million US dollars, the balance of payments deficit is 200 million US dollars, and the savings is 400 million US dollars, then ()
Government spending is $300 million
2. The consumption is US $1.5 billion
3. Consumption plus government spending is $1.6 billion
The investment is 400 million US dollars

According to "investment = private sector savings + government sector savings + foreign sector savings", I = 4-2 + 2 = 4
Note: positive foreign savings are net domestic export deficits
