(13x^2 - 10x + 12) - (9x^2 + 20x - 50)

13x^2 - 10x + 12 - 9x^2 - 20x + 50

13x^2 - 9x^2 = 4x^2

- 10x - 20x = -30x

12 + 50 = 62

4x^2 - 30x + 62

Answer:

4x² - 30x + 62

Step-by-step explanation:

(13x² - 10x + 12) - (9x² + 20x - 50)

first get rid of the parantheses by distributing the -

13x² - 10x + 12 - 9x² - 20x + 50

then combine like terms

4x² - 30x + 62
