Question

fatore:a) x²-x+2x-2
b) y²-4x²
c)y²-8xy+16x²
d)a²+4ab+4b²

Answer 1

x² - x + 2x - 2= x(x-1) + 2(x-1) = (x+2)(x-1)

y² - 4x² = (y-2x)(y+2x)

y² - 8xy + 16x² = (y - 4x)²

a² + 4ab + 4b² = (a + 2b)²

Answer 2

Resposta:

Explicação passo-a-passo:

x² - x + 2x - 2= x(x-1) + 2(x-1) = (x+2)(x-1)

y² - 4x² = (y-2x)(y+2x)

y² - 8xy + 16x² = (y - 4x)²

a² + 4ab + 4b² = (a + 2b)²
