Question

a) (-18x²+8x) : (+2x) =
b) (6x²y-4xy²) : (-2x) =

me ajudem preciso entregar amanhã

Answer 1

a)
( -18x² + 8x )/( 2x ) = 0
2x . ( -9x + 4 )/2x
-9x + 4

b)
( 6x²y - 4xy² )/( -2x )
2x . ( 3xy + 2y² )/ -2x
-3xy² + 2y²

Answer 2

   
    A)   (-18x² + 8x) : (+2x) =
           (-18x² : 2x) + (8x : 2x) =
                 -9x +  4


    B)    (6x²y - 4xy²) : (-2x) =
            6x²y : (-2x) - 4xy² : (-2x) =
                -3xy + 2y² = 2y² - 3xy = y(2y - 3x)
