Hi there!


- 2a(a + b - 5) + 3( - 5a + 2b) + b(6a + b - 8)
First work out the parenthesis.


- 2 {a}^(2) - 2ab + 10a - 15a + 6b + 6ab + {b}^(2) - 8b
Now collect the terms.


- 2a {}^(2) + {b}^(2) + 4ab - 5a - 2b
Next up we can answer our questions.

The coefficient of the a^2 term is...
B) -2

The coefficient of the ab term is...
B) 4

The coefficient of the b term is...
A) -2
