• This Question is Closed
1. midhun.madhu1987

Multiply both numerator and denominator by the conjugate of (7+3i) which is (7-3i)

2. midhun.madhu1987

$(\frac{ 4-5i }{ 7+3i })(\frac{ 7-3i }{ 7-3i })$

3. hockeychick23

15i^2-47i+28/-9i^2+49

4. midhun.madhu1987

$\frac{ 28 - 12i - 35i + 15i ^{2} }{ 7^{2} - (3i)^{2} }$

5. hockeychick23

15i^2-47i+28/49-3i^2

6. midhun.madhu1987

$\frac{ 28 - 12i - 35i + 15i ^{2} }{ 7^{2} - (3i)^{2} }$

7. midhun.madhu1987

This is the next step...Please combine the like terms from the numerator... also simplify the denominator as well... Do you know the value of i^2?

8. hockeychick23

28-47i+15i^2/49-3i^2 i^2= -1 28-47i+15(-1)/49-3(-1) 28-47i-15/52 13-47i/52
