Perform the indicated operation and write and standard form. -7i(6i-3)

Answers

-7i (6i - 3)

Perform the distributed multiplication to eliminate the parentheses:

-7i (6i) - 7i (-3) = -42i² + 21i

IF i = √-1 , then the expression is equal to (42 + 21i) or 21(2 + i) .

$-7i(6i-3)=\n -42\cdot(-1)+21i=\n 42+21i$
