Match each expression to its equivalent standard form.
a. x^2 + x + 2
b. x^2 + 2x + 2
c. x^2 + 4
d. x^2 - 4x + 8
e. x^2 +16
f. x^2- 4x -4
1. (x + 2i)(x -2i)
2. (x - 2 + 2i)(x - 2 - 2i)
3. (x + 1 + i)(x + 1 - i)

Let's expand the products they are all in the form

For the first one we have a=x and b=2i:

For the second one we have a=x-2 and b=2i:

For the third one we have a=x+1 and b=i:

it 2

step-by-step explanation:

8^1/3=2

the image of (6, 9) under a dilation is (4, 6). the scale factor is
