Answer:
A. x^2 - 6x - 16
Step-by-step explanation:
FOIL it
x * x = x^2
2 * x = 2x
-8 * x = -8x
2 * -8 = -16
x^2 + 2x - 8x - 16. combine like terms
x^2 - 6x - 16
Answer:
The midpoints are ( 2, 3).
Step-by-step explanation:
Given that the endpoints are A( 1, 2) and B (3, 4)-
As we know that-
If a line segment AB is with endpoints (
) and (
) then the mid points C are-
C = (
,
)
Here,
A ( 1, 2 ) and B ( 3, 4 )
then the midpoints C are-
C = (
, 
C= ( 4/2 , 6/2 )
C = ( 2, 3 )
Hence the required midpoints are (2, 3).
