ПОМОГИТЕСРОЧНО ДАМ 50 БАЛОВ) Сократите дробь: 5x2 10x3-15x2 Б) 10x-10y 25х2-25y2​

Answer 1

$\frac{5 {x}^{2} }{10 {x}^{3} - 15 {x}^{2} } = \frac{5 {x}^{2} }{5 {x}^{2} (2x - 3)} = \frac{1}{2x - 3}$

$\frac{10x - 10y}{25 {x}^{2} - 25 {y}^{2} } = \frac{10(x - y)}{25( {x}^{2} - {y}^{2} )} = \frac{2(x - y)}{5(x - y)(x + y)} = \\ = \frac{2}{5(x + y)} = \frac{2}{5x + 5y}$
