Simplify the given expression: (7 − 3i) • (2 − i)

OpenStudy (xapproachesinfinity):

Do you know how to distribute (a+b)(c+d)

OpenStudy (solomonzelman):

if i is a variable, leave i^2 as it is, if it's imaginary, then i^2=-1

OpenStudy (nurali):

(7 − 3i) • (2 − i) 14-7i-6i+3i^2 i^2=-1 14-7i-6i-3 11-13i

OpenStudy (abbyrose0105):

Yes, I used the FOIL rule and combined like terms. These are my 4 options I got the second one but I don't think that's right 4 + i 14 + 3i 11 − 13i 14 − 10i

OpenStudy (xapproachesinfinity):

OpenStudy (abbyrose0105):
