Question

What is the simplified form of this expression (-3x^2+4x)+(2x^2-x-11)

Answer 1

Given expression:

`(-3x^2+4x)+(2x^2-x-11)`

To simplify the expression, it is needed to open the parentheses.

`\implies (-3x^2+4x)+(2x^2-x-11)`

`\implies -3x^2+4x+2x^2-x-11`

To further simplify the expression, let us combine like terms.

`\implies -3x^2+4x+2x^2-x-11`

`\implies x^(2) (-3 + 2)+x(4-1)-11`

Now, simplify the expression as needed.

`\implies x^(2) (-3 + 2)+x(4-1)-11`

`\implies x^(2) (-1)+x(3)-11`

Finally, open the parentheses to get the simplified form

`\implies x^(2) (-1)+x(3)-11`

`\implies \boxed{\bold{-x^(2) +3x-11}}`

`\text{Therefore, the simplified expression is} \ \boxed{-x^(2) +3x-11}`

Answer 2

SolutioN :

`\bf \: \star ( - 3x^(2) + 4x) + (2 {x}^(2) - x - 11)`

`\longrightarrow \bf \: - 3 {x}^(2) + 4x + 2 {x}^(2) - x - 11`

`\longrightarrow \bf \: - 3 {x}^(2) + 2 {x}^(2) + 4x - x - 11`

`\longrightarrow \boxed{\bf \: - {x}^(2) + 3x - 11}`
