Can i have some ? algebra 2 is not my strong suit.
multiply: i(4−7i)

We have the following equation:

i(4-7i)

Multiplying:

4i - 7(i^2)

So we know that i = sqrt(-1), then i^2 = -1.

For that reason:

4i - 7(i^2) = 4i - 7(-1) = 4i + 7

So the answer is: 4i +7

none of the above.

for one of the equations to be used in the process, there has to be a term in the equation since squared is .

since there is only a term in the first equation, we cannot derive a from completing the square.

solving with completing the square
