Question

Розкладіть на множники 1) х²-4=
2) 36m²-100n²=
3) a⁴-в⁶=
4) 0.81y-400в¹²

Answer 1

Объяснение:

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

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

$36 {m}^{2} - 100 {n}^{2} = (6m - 10n)(6m + 10n)$

${a}^{4} - {b}^{6} = ( {a}^{2} - {b}^{3})( {a}^{2} + {b}^{3} )$

$0.81y - 400 {b}^{12} = (0.9 \sqrt{y} - 20 {b}^{6} )(0.9 \sqrt{y} + 20 {b}^{6})$

Answer 2

Объяснение:

1)(x-2)(x+2)

2)(6m-10n)(6m+10n)

3)(a²-b³)(a²+b³)

4)(0.9y-20b⁶)(0.9y+20b⁶
