Question

4a+3b-2a-b i need the the sum ​

Answer 1

Answer:

Hope this helps you thanku (◕ᴗ◕✿)

Step-by-step explanation:

It is instructed to subtract (2a−3b+4c) from the sum of (a+3b−4c),(4a−b+9c) and (−2b+3c−a).

It is instructed to subtract (2a−3b+4c) from the sum of (a+3b−4c),(4a−b+9c) and (−2b+3c−a).So, First we will do the sum of the three given polynomials,Sum =(a+3b−4c)+(4a−b+9c)+(−2b+3c−a)=(a+4a−a)+(3b−b−2b)+(−4c+9c+3c)=4a+8cNow, we can perform the subtraction,∴ Required difference=(4a+8c)−(2a−3b+4c)=4a+8c−2a+3b−4c=2a+3b+4c

Answer 2

questions = 4a+3b-2a-b

answer. = 4a-2a+3b-b

= 2a+2b

= 4ab
