Wil give extraaa pointsss and brainliest just for the answers say the whole thing so its easier

Here are your fill-ins:

r = 1 is a zero, so (r-1) is a factor.

r = -1 is a zero, so (r+1) is a factor.

The remainders from synthetic division are 0 each time.

See the attachment for the synthetic division numbers.

_____

The reduced quadratic is ...

... x² -6x +13 = 0

Solving by completing the square, we have ...

... (x -3)² = -4

... x = 3 ± 2i

_____

The quadratic formula would tell you ...

... x = (-(-6) ± √((-6)² -4(1)(13)))/(2·1) = (6±√-16)/2 = 3±2i

the least value out of the data shown is 5, maybe if you post a picture with it i could a little more.

step-by-step explanation:

factor trees are nice.
