Question

Solve 2x2 - (3 + 7i) x - (3 - 9i) = 0​

Answer 1

Answer:

2x2-(3+7i)x-(3-9i)=0

D = b^2 - 4ac

b = -(3-7i)

c = (9i-3)

D = (3-5i)^2

Now apply quadratic equation root formula

x = 3i , (3+i)/2

Hope this helps

Answer 2

Answer:

x = 3i , (3+i)/2

Step-by-step explanation:

2x2-(3+7i)x-(3-9i)=0

D = b^2 - 4ac

b = -(3-7)

c = (9i-3)

D = (3-5i)^2 =

Now apply quadratic equation root formula

x = 3i , (3+i)/2
