Last,

What is the simplified expression for –2a2b + a2 – 5ab + 3ab2 – b2 + 2(a2b + 2ab)?

Solution

1.

-2*a^2b + a^2 - 5ab + 3*ab^2 - b^2 + 2*(a^2b + 2ab)

= a^2 - b^2 - ab + 3ab^2

Correct option is D.

2.

2|6 + p| - 3p^3

when p = -2

2*|6 - 2| - 3*(-2)^3

= 2*4 - 3*(-8) = 32

Correct option is C.

3.

rate of change = [f(b) - f(a)]/(b - a)

= [f(5) - f(1)]/(5 - 1)

= [(17 - 5^2) - (17 - 1^2)]/4

= (-8 - 16)/4 = -6

Correctoption is A.
