Answer:

38

Step-by-step explanation:

2(a^{2}+ab) + 3 - ab

= 2a^{2} + 2ab + 3 - ab

= 2a^{2} + ab + 3

= 2x5^{2} + 5x(-3) + 3

= 50 - 15 + 3

= 38

The functions f(x) and g(x) are defined below.
schepotkina [342]
For this case we have the following polynomials:
 f (x) = 21x ^ 2 + 13x - 20

g (x) = -3x - 4
 To divide the polynomials we must follow the following steps:
 1) Same base, the exponents are added.
 2) Only terms that have the same exponent can be added or subtracted.
 3) If the remainder is zero, the division is exact.
 Answer:
 
f (x) / g (x) = -7x + 5

 Note: see attached image for the solution.
