Question

Find the sum or difference. The answer must be in standard form

(x² - 4x + 3)+(3x² - 3x -5)

Answer 1

`\huge\boxed{\sf 4x\² - 7x - 2}`

Explanation:

Given expression:

= (x² - 4x + 3) + (3x² - 3x - 5)

• Take the brackets off

= x² - 4x + 3 + 3x² - 3x - 5

• Combine like terms

= x² + 3x² - 4x - 3x + 3 - 5

= 4x² - 7x - 2

`\rule[225]{225}{2}`
