Question

вывести общий множитель за скобки
3а+3b=
16+4y=
-24s-12t=
сократить дробь
x-y/2y-2x=
4a^2-12ab+9b2/15b-10a=
срочно ​

Answer 1

3а+3b= 3 (a+b)

16+4y= 4 (4+y)

-24s-12t= -12 (2s+t)

•

x-y / 2y-2x = x-y / 2 (y-x) = -1(y-x) / 2(y-x) = -1/2

4a^2-12ab+9b2 / 15b-10a = (2a - 3b)² / 5 (3b - 2a) = (2a - 3b)² / -5 (3b - 2a) = 2a-3b / -5

Answer 2

3а+3b= 3 (a+b)

16+4y= 4 (4+y)

-24s-12t= -12 (2s+t)

(х-y) / (2y-2x) = (x-y )/ 2 (y-x) = -1(y-x) / 2(y-x) = -1/2=-0.5

(4a²-12ab+9b²)/( 15b-10a) = (2a - 3b)² / 5 (3b - 2a) = (-2a + 3b)² /(5 (3b - 2a) = (3b -2а)/ 5
