Answer:
f(x) = x^3 + 4x^2 - 7x - 28
Step-by-step explanation:
If the roots of this cubic function are Square root of seven, -Square root of seven, -4, then the factors must be (x^2 - 7)(x + 4).
Multiplying this out, we get f(x) = x^3 + 4x^2 - 7x - 28.
Note: Please use " ^ " to indicate exponentiation.
Answer:
K/(4+9b) = a
Step-by-step explanation:
K = 4a + 9ab
Factor out a on the right hand side
K = a(4 + 9b)
Divide each side by (4+9b)
K/(4+9b) = a(4 + 9b)/(4+9b)
K/(4+9b) = a
