Question

please are very need that I really need it please answer the attached question and don't give irrelevant answers​

Answer 1

1. 1) Y^3 - (2x+3) 2) 4mn * 7x = 28 mnx

2) 1) [2x-(4y+2x-5y) -y] = 2x+y -2x - y = 0

2) {5[2(c-d) - c ]+3d} = 5( 2c-2d -c) + 3d

= 5c - 7d

3)

1) 72xy - 42 y = 18xy - 12 y = 3xy -2y = y( 3x-2)

2) 9mn-45m-135my =mn-5m-15my

= m(n-5-15y)
