as the product of 90 degrees and 20 degrees
30x60=1800
90x20=1800
The answer to this question is d because 7 is in the ten-thousand's place and another 7 is in the thousand's place.
Answer:
So it looks like the given zeros are 2i and -3. We have to work backwards.
x = -3 and x = 2i
For -3, we know that out factored form before would have been x + 3
For 2i, that means we took the square root of negative number because it is imaginary. So that means out factored for x2 + 4
So if we put these together:
(x2 + 4)(x + 3) = x3 + 3x2 + 4x + 12
