Question

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

Answer 1

$\huge \mathfrak{Solution : }$

Simplification :

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

• ${x}^{2} + 2 {x}^{2} + 3x - 4x + 2 + 1$

• $3 {x}^{2} - x + 3$

Answer 2

Answer:

$3x^2-x+3$

Step-by-step 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:-

$3x^2-x+2+1$

$3x^2-x+3$
