(3 + 6i)(3 + 7i)
FOIL: First, Outside, Inside, and Last
3 x 3 = 9
3 x 7i = 21i
6i x 3 = 18i
6i x 71= 42i
9 + 21I + 18I + 42I = 9 + 81I
a = 9
B = 81I
You have to do 4 times the 8 which is 24. Then find the adding for the -6. 1*6 2*6 3*6 4*6 , 4*6 is 24 so your answer would be (x-4) (x+6)
First we have to multiply the numerator and the denominator by 5:
