The point-slope formula:
We have (-2, 1) and (1, 7).
Substitute:
Answer:
4b^4+15b^3
Step-by-step explanation:
(24b^3+90b^2)
6b
Divide like terms.
24/6=4
90/6=15
(4b^3+15^2)........ Now since you have a "b" left from the 6 you add that b two the previous "b"
There you have it, your answer will be = (4b^4+15^3)

Answer:
c
Step-by-step explanation:
Given the roots are x = - 1 + 4i and x = - 1 - 4i then the factors are
(x - (- 1 + 4i))(x - (- 1 - 4i))
= (x + 1- 4i )(x + 1 + 4i )
= (x + 1)² - 16i² → [ i² = - 1 ]
Expand and simplify
= x² + 2x + 1 + 16
Hence
x² + 2x + 17 = 0 → c
