Question

представить в виде многочлена
1) (у-6)²=
2) (2а-3б)²=
3) (3х+х³)²=
4) (m-6) (m+6)=
5) ( 7x+10y) (10y-7x)= ​

Answer 1

$1) \: (y - 6) {}^{2} = y {}^{2} - 12y + 36 \\ 2) \: (2a - 3b) {}^{2} = 4a {}^{2} - 12ab + 9b {}^{2} \\ 3) \: (3x + x {}^{3} ) {}^{2} = 9x {}^{2} + 6x {}^{4} + x {}^{6} \\ 4) \: (m - 6)(m + 6) = m {}^{2} - 36 \\ 5) \: (7x + 10y)(10y - 7x) = 100y {}^{2} - 49x {}^{2}$
