It is 30 points and will give brainliest Use Pascal's Triangle to solve this equation. SHOW WORK:
(2a - b)²

4a2−4ab+b2

Step-by-step explanation:

(2a−b)2 =(2a+−b)(2a+−b)

=(2a)(2a)+(2a)(−b)+(−b)(2a)+(−b)(−b)  

 Sooo our equation =4a2−2ab−2ab+b2

Hoped I helped -

x=half

step-by-step explanation:

take the logarithm of both sides (the base of the log doesn't matter):

apply the exponent property - this says that :

distribute the log terms on both sides:

group like terms together:

divide through both sides by the coefficient on :

you can do some additional rewriting here using the properties of the logarithm to simplify things if you like:
