Question

alguem me ajuda por favor​

Answer 1

a)5x-7xy

b)10ab+5a

c)-4xy+4y

d)14x⁴y¹¹

Answer 2

Resposta:

a) x(5 -7y)

b) 5a( 2b+1)

c) -4y(x²-y)

d)2xy(5xy⁵+4xy²)

Explicação passo-a-passo:

a) 7x - 10xy + 3xy -2x= 5x - 7xy= x(5 -7y)

b)ab + 6a + 9ab - a= 10ab +5a= 5a( 2b+1)

c)x²y -4y² +8y² -5x²y= -4x²y +4y²= -4y(x²-y)

d)4x²y⁶ +6x²y⁶ -3x²y³ +7x²y³= 10x²y⁶ + 4x²y³= 2xy(5xy⁵+4xy²)
