Given: (16-5i)*(-2-i)
\n" ); document.write( "Let
\n" ); document.write( "(1) P = (16-5i)*(-2-i)
\n" ); document.write( "All you need to do is FOIL the binomials of (1) to get
\n" ); document.write( "(2) P = 16*(-2) + 16*(-i) -5i*(-2) -5i*(-i) or
\n" ); document.write( "(3) P = -32 - 16*i +10i + 5i^2 or
\n" ); document.write( "because i^2 = -1 we get
\n" ); document.write( "(4) P = -32 - 16*i +10i - 5 or
\n" ); document.write( "(5) P = -32 - 6i - 5 or
\n" ); document.write( "(6) P = -37 - 6i
\n" ); document.write( "Answer: (16-5i)*(-2-i) = -37 - 6i\r
