asked • 02/12/20g is a degree 5 polynomial that passes through the origin, has zeros i and 3−i, and g(−4)=−13600. Find the equation for g.
Use u for your input. Simplify your answer so that it has only real numbers as coefficients.

g(u) = a(u- i)(u + i)(u - (3 - i))(u - (3 + i))(u - 0)
g(u) = a(u2 + 1)(u2 + 10)(u)
-13600 = a((-4)2 + 1)2((-4)2 + 10)2(-4)
Can you solve for a and somplete?
