Question

1-m в 4 степени =?
6xy-18y-6x+18=?
-8c во 2 степени +16c-8

Answer 1

Объяснение:

$1 - {m}^{4} = (1 + {m}^{2} )(1 - {m}^{2} ) = (1 + {m}^{2} )(1 + m)(1 - m)$

$6xy - 18y - 6x + 18 = 6y(x - 3) - 6(x - 3) = (x - 3)(6y - 6) = 6(x - 3)(y - 1)$

$- 8 {c}^{2} + 16c - 8 = - 8( {c}^{2} - 2c + 1) = - 8 {(c - 1)}^{2}$
