Answer:
The coefficient of a² term is -2, coefficient of an term is 4 and coefficient of b term is -2.
Step-by-step explanation:
The given expression is
[tex]-2a(a+b-5)+3(-5a+2b)+b(6a+b-8)[/tex]
Using distributive property,
[tex]-2a^2-2ab+10a-15a+6b+6ab+b^2-8b[/tex]
Combine like terms.
[tex]-2a^2+(6ab-2ab)+(10a-15a)+b^2+(6b-8b)[/tex]
[tex]-2a^2+4ab-5a+b^2-2b[/tex]
From the this expression we can say that the coefficient of a² term is -2, coefficient of an term is 4 and coefficient of b term is -2.
