Question

РЕШИТЬ УРАВНЕНИЕ С ПОМОЩЬЮ ФОРМУЛ СОКРАЩЕННОГО УМНОЖЕНИЯ

Answer 1

1
3(x²-2xy+y²)/[6(x-y)(x+y)]=(x-y)²/[2(x-y)(x+y)]=(x-y)/[2(x+y)]
2
(m+3n)²/[4m(m+3n)]=(m+3n)/4m

Answer 2

$frac{3x^2-6xy+3y^2}{6x^2-6y^2} = frac{3(x^2-2xy+y^2)}{6(x^2-y^2)} =frac{3cdot (x-y)^2}{6(x-y)(x+y)} = frac{x-y}{2cdot (x+y)} \\\ frac{m^2+6mn+9n^2}{4m^2+12mn} = frac{(m+3n)^2}{4m(m+3n)} = frac{m+3n}{4m}$
