The towel on the wall… It’s our ancient custom. There was not a single Ukrainian house , which would not be decorates with towels. A house without a towel was compared with a family without children. A towel symbolized not only aesthetic taste , it was a face of a house and of a hostess. The towels proved that the hostess was tidy and hard-working.
A newly-born child was handed with the towel, guests were met with bread and salt on the towel. A son , a husband, a father were seen off with the towel. While getting married the newly-formed family was standing on a towel too. Bread and salt on an embroidered towel were a symbol of hospitality of the Ukrainian people. To take the towel , to kiss bread symbolized unity, peace, love , understanding among people. This custom has a good tradition in our country.
Towel were used in different ceremonies and in everyday life as well: for wiping a face and hands, for drying dishes, for decorating the houses, for presenting dear people. The ornaments and colours of towels were different in different regions. A lot of songs about the embroidered towel have been created in Ukraine. Объяснение:

Найдем дискриминант квадратного уравнения:
D = b2 - 4ac = 42 - 4·1·8 = 16 - 32 = -16
Так как дискриминант меньше нуля, то уравнение не имеет действительных решений.
4x2 - 12x + 9 = 0
Найдем дискриминант квадратного уравнения:
D = b2 - 4ac = (-12)2 - 4·4·9 = 144 - 144 = 0
Так как дискриминант равен нулю то, квадратное уравнение имеет один действительных корень:
x = 122·4 = 1.5
3x2 - 4x - 1 = 0
Найдем дискриминант квадратного уравнения:
D = b2 - 4ac = (-4)2 - 4·3·(-1) = 16 + 12 = 28
Так как дискриминант больше нуля то, квадратное уравнение имеет два действительных корня:
x1 = 4 - √282·3 = 23 - 13√7 ≈ -0.21525043702153024
x2 = 4 + √282·3 = 23 + 13√7 ≈ 1.5485837703548635
2x2 - 9x + 15 = 0 Найдем дискриминант квадратного уравнения: D = b2 - 4ac = (-9)2 - 4·2·15 = 81 - 120 = -39 Так как дискриминант меньше нуля, то уравнение не имеет действительных решений.The towel on the wall… It’s our ancient custom.
