Answer:
Step-by-step explanation:
roots are (2+3i) and (2-3i)
reqd. eq. is (x-2-3i)(x-2+3i)=0
or (x-2)²-(3i)²=0
or x²-4x+9-9i²=0
or x²-4x+9+9=0
or x²-4x+18=0

Answer:
1/r^56
Step-by-step explanation:
Not sure if you did a typo there or what cus 7 x 8 should be 56
Whenever the power of a number is negative, you flip. So r^-7 becomes 1/r^7
Remove the bracket and distribute 8 to the power of 1 and r^7
1 to the power of 8 will still be 1, r^7 x 8 = r ^ 56
