Question

(-0,8)^2-(-1,6)/ -4+2

Answer 1

$\frac{( - 0.8) - ( - 1.6)}{ - 4 + 2} = \\ \\ \frac{( - \frac{4}{5})^{2} + 1.6 }{ - 2} = \\ \\ \frac{ \frac{16}{25} + \frac{8}{5} }{ - 2} = \\ \\ \frac{ \frac{56}{25} }{ \frac{ - 2}{1} } = \\ \\ - \frac{28 }{25}$

Answer 2

$\frac{(-0,8)^2-(-1,6)}{-4+2} = \frac{+0,64+1,6}{-2} = \frac{2,24}{-2} =-1,12$
