fatoração 0.04x^2-0.09

Solução

fatoração

0.04 x^{2} - 0.09

(0.2 x + 0.3) (0.2 x - 0.3)

Passos da solução

0.04 x^{2} - 0.09

Reescrever

0.04 x^{2} - 0.09

como

(0.04 x)^{2} - (0.09)^{2}

= (0.04 x)^{2} - (0.09)^{2}

Aplicar a regra da diferença de quadrados:

x^{2} - y^{2} = (x + y) (x - y)

(0.04 x)^{2} - (0.09)^{2} = (0.04 x + 0.09) (0.04 x - 0.09)

= (0.04 x + 0.09) (0.04 x - 0.09)

0.04 = 0.2

= (0.2 x + 0.09) (0.04 x - 0.09)

0.09 = 0.3

= (0.2 x + 0.3) (0.04 x - 0.09)

0.04 = 0.2

= (0.2 x + 0.3) (0.2 x - 0.09)

0.09 = 0.3

= (0.2 x + 0.3) (0.2 x - 0.3)
