How do i break up (x^2 -4x+8) into like (x blabla)(x blabla)

You can't break it in the form of (x blabla)(x blabla) since there are no real roots.

Step-by-step explanation:

Proof:

x^2 - 4x + 8 = 0

(x - 2)^2 = - 4

x=2 + 2i or x= 2 - 2i (Complex numbers)

the least common denominatore of 7 and 2 is 9

step-by-step explanation:

7+2=9

in the attachment.   i didn't see your choices.   the word which means there is choices.

step-by-step explanation:

(x,y)

x tells you how much left or right you go from the origin

y tells you how much down or up you go from the origin

so for example (-3,2), you go left 3 and up twice. i denoted which of the ordered pairs is which in my graph.
