9. X=7. 7-8=-1
8. X=18. 18-7=11
Answer:
Step-by-step explanation:
we have the expression
Convert to vertex form
where
a is the leading coefficient
(h,k) is the vertex
Complete the square
Rewrite as perfect squares
so
The coefficient a =1
The vertex is the point (-2,-2)
We have to find the quotient :
( 4 x³ y + 12 x² y³ - 20 x y ) / ( 4 x y ) =
= 4 x y ( x² + 3 x y² - 5 ) / ( 4 x y ) = ( Then 4 x y will be cancelled )
= x² + 3 x y² - 5
Answer:
D ) x² + 3 x y² - 5
