Step-by-step explanation:
For this case we have:
Be a function of the form
Where:
If we want to find f (-2), we substitute , then:
Since we have a negative root, the result will be given by complex numbers. By definition:
So:

Please give me brainliest ;)
Step-by-step explanation:
s = side of square
l = length of rectangle = s + 3 cm
w = width of rectangle = s - 2 cm
s² + 30 = (s + 3)(s - 2) = s² + - 2s + 3s - 6 = s² + s - 6
30 = s - 6
s = 36 cm
