One solution each is given for four quadratic equations. Assuming that each quadratic equation has two solutions, what is the second solution
for each equation?
I= 5 + 4i
I= 4 - 5
1 =
-5
4i
1 =
-4 + 51
I = 4 + 51
>
I = 5 - 4
= - 4 - 5

Step-by-step explanation:

If one solution of a quadratic equation is a complex number (a + bi),

Other solution of the equation will be the conjugate of the first solution.

So the other solution will be in the form of (a - bi)

If one solution is, x = -4 - 5i

Other solution will be, x = -4 + 5i

If one solution is, x = 4 + 5i

Other solution will be, x = 4 - 5i

If one solution is, x = 5 - 4i

Other solution will be, x = 5 - 4i

I believe if wrong sorry :(

-10i^2-4i

step-by-step explanation:

evaluate for p=2,q=5i

(2−4)(2+5i)i

(2−4)(2+5i)i

=−10i2−4i
