Question

Здравствуйте! Можете пожалуйста помочь?
Только столбик А

Answer 1

${a}^{2} - 9 = (a - 3)(a + 3)$

$4 - {y}^{2} = (2 - y)(2 + y)$

$9 {x}^{2} - 4 = (3x - 2)(3x + 2)$

$9 {a}^{2} - 16 {m}^{2} = (3a - 4m)(3a + 4m)$

Возможно тут не +, а минус

${b}^{2} + 1$

${b}^{2} - 1 = (b - 1)(b + 1)$

$9 - {b}^{4} = (3 - {b}^{2} )(3 + {b}^{2} )$

$48 {m}^{2} - {n}^{2} = (4 \sqrt{3} m - n)(4 \sqrt{3} m + n)$

$36 {m}^{6} - 49 {k}^{4} {n}^{2} = (6 {m}^{3} - 7 {k}^{2} n)(6 {m}^{3} + 7 {k}^{2} n)$

${x}^{6} - 1.44 = ( {x}^{3} - 1.2)( {x}^{3} + 1.2)$

${y}^{12} - 16 = ( {y}^{6} - 4)( {y}^{6} + 4) = ( {y}^{3} - 2)( {y}^{3} + 2)( {y}^{6} + 4)$

$9 {a}^{2} {b}^{2} - 64 {x}^{4} = (3ab - 8 {x}^{2} )(3ab + 8 {x}^{2} )$
