Question

(8a² - 7a - 10 ) - (3a² - 5a - 10)

Answer 1

Given : (8a² - 7a - 10 ) - (3a² - 5a - 10)

To Find :  Simplify

Solution:

 (8a² - 7a - 10 ) - (3a² - 5a - 10)

(-)(-) =  +

(-)(+) = -

(+)(-) = -

(+)(+) = +

=  (8a² - 7a - 10 )  - 3a²  + 5a + 10

= 8a² - 7a - 10   - 3a²  + 5a + 10

Combine like terms

=  8a²   - 3a² - 7a   + 5a  - 10 + 10

= 5a² - (7a - 5a) -(10 - 10)

= 5a² - 2a - 0

= 5a² - 2a

(8a² - 7a - 10 ) - (3a² - 5a - 10) = 5a² - 2a
