Step-by-step explanation:
Hello,
As the polynomial has only real coefficients, it means that 3-i is a zero too, because we apply the Conjugate Zeros Theorem.
It means that we can write the expression as below, k being a real number that we will have to identify.
And for x = 0, y = -90 so we can write
-90=k*3*10, meaning that k=-3
Hope this helps.
