PLEASE HELP CORRECT ANSWER WILL GET BRAINLIEST!! Which shows equivalent expressions? a squared + 3 b minus 2 a squared = 3 a squared + 3 b minus 4 a squared a squared + 3 b minus 2 a squared = 3 a squared + 4 b minus 4 a squared Negative a squared + 3 b minus 2 a squared = 3 a squared + 3 b Negative a squared + 3 b + 2 a squared = 3 a squared + 4 b minus 2 a squared (options are down below also)

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

Step-by-step explanation:

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

Combine like terms

a^2 +3b  = a^2 +4b

-a^2 + 3b -2a^2 = 3a^2 + 3b

Combine like terms

-3a^2 +3b  = 3a^2 +3b

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

Combine like terms

-3a^2 +3b  = -a^2 +4b

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

Combine like terms

-a^2 +3b  = -a^2 +3b

The left side is the same as the right

set each factor equal to 0

4x-3 = 0

2x-1 = 0

solve for x.

4x-3=0

4x=3

x= 3/4

solve for x. 

2x-1= 0

2x= 1

x= 1/2

eventually after a few more steps, your answer should be 1/2 is less than or equal to x and 3/4 is greater than or equal to x
