Divide and simlplify 52i/5+i

2+10i

Step-by-step explanation:

You should multiply by the conjugate,

which is 5-i in this problem.

(52i/(5+i))((5-i)/(5-i))=(260i-52i^2)/(25-i^2)

=(260i+52)/26=[26(10i+2)]/26

simplify, the 26's cancel out,

leave you with 10i+2.

Remember that i^2=i*i=-1.

5+2x=a
