Нужно сократить,помогите пожалуйста,очень срочно!!!!!!!!!!!!!! 1) ax^2-ax/ax 2) ab/ab-ab^2 3) 3m^2-6m/m^2-4 4) 4-n^2/8n-4n^2 5) b^2-b/ab-b 6) mn+n^2/mn+n 7) p^2-2p/p^2-4p+4 8) q^2+2q/q^2+4q+4
1) = ( ax * ( x - 1)) / ax = x - 1 2) = ab / ( ab * ( 1 - b )) = 1 / ( 1 - b ) 3) = ( 3m * ( m - 2 )) / ( m - 2)*(m + 2) = 3m / ( m + 2 ) 4) = ( 2 - n)*(2 + n ) / ( 4n * ( 2 - n )) = ( 2 + n ) / 4n 5) = ( b * ( b - 1)) / ( b * ( a - 1 )) = ( b - 1) / ( a - 1 ) 6) = ( n * ( m + n )) / ( n * ( m + 1 )) = ( m + n) / ( m + 1 ) 7) = ( p * ( p - 2)) / ( p - 2)*(p - 2) = p / ( p - 2 ) 8) = ( q * ( q + 2)) / ( q + 2)*( q + 2) = q /( q + 2 )
