Answer:

- 2a² - 5a + 4ab - 2b + b²

Step-by-step explanation:

Distributing the parenthesis gives

= - 2a² - 2ab + 10a - 15a + 6b + 6ab + b² - 8b ( collect like terms )

= - 2a² + (10a - 15a) + (- 2ab + 6ab) + (6b - 8b) + b²

= - 2a² - 5a + 4ab - 2b + b²

------------------------------------------------------

coefficient of the a² term is - 2

coefficient of the ab term is + 4

coefficient of the b term is - 2

For the functions f(x)=−7x^2−x and g(x)=9x^2−4x, find (f−g)(x) and (f−g)(1)
musickatia [10]

Answer:

See below.

Step-by-step explanation:

f(x)=-7x^2-x\\g(x)=9x^2-4x\\(f-g)(x)=f(x)-g(x)\\(f-g)(x)=(-7x^2-x)-(9x^2-4x)\\(f-g)(x)=-7x^2-x-9x^2+4x\\(f-g)(x)=-16x^2+3x\\\\(f-g)(1)=-16(1)^2+3(1)\\(f-g)(1)=-16+3=-13
