Please solve the sum step by step​

Answer 1

Answer:

∴ the smaller number = 35a³ +2a² + 11a - 9

Step-by-step explanation:

given,

  let the smaller number be x,

the larger number = 20a³ + 10a² + 6a - 6

the difference between the numbers = -15a³ + 8a² -5a + 3

     

here,

  (20a³ + 10a² +6a- 6) - x =  -15a³  + 8a² - 5a + 3

or, 20a³ + 10a² + 6a -6 = (-15a³ + 8a² - 5a + 3) + x

or, (20a³ + 10a² + 6a - 6 ) - (-15a³ + 8a² - 5a + 3) = x

or, x = 20a³ + 10a² + 6a - 6 + 15a³ - 8a² + 5a - 3

or, x = 20a³ + 15a³ + 10a² - 8a² + 6a + 5a -6 -3

∴ x = 35a³ + 2a² + 11a- 9
