Question

(please help me with Complete
solution and explanation please )​

Answer 1

Explanation:

1. 2x

2. m^2 - 2

3. x^2 + 3x - 2

4. m - 2n + 3

You can just simply cancel out the given answers to the given problem.

1. 4x^2 - 2x = ___ (2x + 1)

4/2 = 2

x^2 - x is just x^2-1 so x.

= 2x

To check the answer, 2x (2x + 1) = 4x^2 - 2x

Answer 2

#1

`\\ \rm\star\leadsto \underbrace{2x}(2x+1)`

`\\ \rm\star\leadsto 4x^2+2x`

#2

`\\ \rm\star\leadsto n\underbrace{(m^2-2)}`

`\\ \rm\star\leadsto m^2n-2n`

#3

`\\ \rm\star\leadsto x\underbrace{(x^2+3x-2)}`

`\\ \rm\star\leadsto x^3+3x^2-2x`

#4

`\\ \rm\star\leadsto 2mn\underbrace{(m-2n+3)}`

`\\ \rm\star\leadsto 2m^2n-4mn^2+6mn`
