Question

Simplify (2x2−4x+5)+(x2+3x−7)and put in standard form.

Answer 1

3x^2 - x - 2 (simplified)

3x^2 - x = 2 (standard form)

Explanation:

Answer 2

`3x^2 - x - 2`

Explanation:

Step 1: Combine like terms

`(2x^2- 4x + 5) + (x^2 + 3x - 7)`

`2x^2 - 4x + 5 + x^2 + 3x - 7`

`(2x^2 + x^2) + (-4x + 3x) + (5 - 7)`

`3x^2 - x - 2`

Answer:
`3x^2 - x - 2`
