Question

Simplify the following polynomial and write the answer in standard form. (x2+3x+2)+(2x2 - 4x +1​

Answer 1

`3x^2-x+3`

Explanation:

`\left(x^2+3x+2\right)+\left(2x^2-4x+1\right)`

⇒ Remove parentheses:-

`x^2+3x+2+2x^2-4x+1`

⇒ Combine like terms:-

`x^2+2x^2+3x-4x+2+1`

⇒ Add similar elements:-

`3x^2-x+2+1`

`3x^2-x+3`

Answer 2

`\huge \mathfrak{Solution : }`

Simplification :

• 
  `({x}^(2) + 3x + 2) + (2 {x}^(2) - 4x + 1)`

• 
  `{x}^(2) + 2 {x}^(2) + 3x - 4x + 2 + 1`

• 
  `3 {x}^(2) - x + 3`
