Question

Помогите пожалуйста, срочно!!!!

10) 14x²y^5+7y^7 x³=

11) 12a²b²+18a^5-16ab^6=

12) (x-6)(2x+3)+(6-x)(x+6)=

13)2m²(m+5)²-4m³(5+m) =

Answer 1

10) 14x²y⁵ + 7y⁷x³ = 7x²y⁵(2 + xy²)

11) 12a²b² + 18a⁵ - 16ab⁶ = 2a(6ab² + 9a⁴ - 8b⁶)

12) (x - 6)(2x + 3) + (6 - x)(x + 6) = (x - 6)(2x + 3) - (x - 6)(x + 6) =

= (x - 6)(2x + 3 - x - 6) = (x - 6)(x - 3)

13) 2m²(m + 5)² - 4m³(5 + m) =2m²(m + 5)( - 2m) = - 4m³(m + 5)

Answer 2

Ответ:

$10)14 {x}^{2} {y}^{5} + 7 {y}^{7} {x}^{3} = \\ = 7 {x}^{2} {y}^{5} (2 +x {y}^{ 2})$

$11)12 {a}^{2} {b}^{2} + 18 {a}^{5} - 16a {b}^{6} = \\ = 2a(6a {b}^{2} + 9 {a}^{4} - 8 {b}^{6} )$

$12)(x - 6)(2x + 3) + (6 - x)(x + 6) = \\ = (x - 6)(2x + 3) - (x - 6)(x + 6) = \\ =(x - 6)(2x + 3 - x - 6) = \\ = (x - 6)(x - 3)$

$13)2 {m}^{2} {(m + 5)}^{2} - 4 {m}^{3} (5 + m) = \\ = 2 {m}^{2} (m + 5)(m + 5 - 2m) = \\ = 2 {m}^{2} (m + 5)(5 - m)$
