Question

Can someone plz help me

Answer 1

Answer:

The answer is C. 5a² - 4a + 1

Step- by- Step:

First you want to Distribute the Negative Sign:

= 10a² + 3 − 5a + −1 (2 + 5a² − a)

= 10a² + 3 + −5a + (−1) (2) + −1 (5a²) + −1 (−a)

= 10a² + 3 + −5a + −2 + −5a² + a

Add Like Terms:

= 10a² + 3 + −5a + −2 + −5a² + a

= (10a² + −5a²) + (−5a + a )+( 3+ −2)

= 5a² + −4a + 1

Happy To Help! :)
