the rise of the communist party of china
Answers
Answer:
The CCP was founded in 1921, chiefly by Chen Duxiu and Li Dazhao. The party grew quickly, and by 1949 it had driven the Kuomintang (KMT)'s Nationalist Government from mainland China to Taiwan after the Chinese Civil War, leading to the establishment of the People's Republic of China on 1 October 1949.

Equation at the end of step 1
(32t2 - 64t) - 64 = 0
STEP

:
Trying to factor by splitting the middle term
2.1 Factoring 9t2-64t-64
The first term is, 9t2 its coefficient is 9 .
The middle term is, -64t its coefficient is -64 .
The last term, "the constant", is -64
Step-1 : Multiply the coefficient of the first term by the constant 9 • -64 = -576
Step-2 : Find two factors of -576 whose sum equals the coefficient of the middle term, which is -64 .
-576 + 1 = -575
-288 + 2 = -286
-192 + 3 = -189
-144 + 4 = -140
-96 + 6 = -90
-72 + 8 = -64 That's it
Step-3 : Rewrite the polynomial splitting the middle term using the two factors found in step 2 above, -72 and 8
9t2 - 72t + 8t - 64
Step-4 : Add up the first 2 terms, pulling out like factors :
9t • (t-8)
Add up the last 2 terms, pulling out common factors :
8 • (t-8)
Step-5 : Add up the four terms of step 4 :
(9t+8) • (t-8)
Which is the desired factorization
Equation at the end of step
2
:
(t - 8) • (9t + 8) = 0

Theory - Roots of a product
3.1 A product of several terms equals zero.
When a product of two or more terms equals zero, then at least one of the terms must be zero.
We shall now solve each term = 0 separately
In other words, we are going to solve as many equations as there are terms in the product
Any solution of term = 0 solves product = 0 as well.
