Question

please give me answer​

Answer 1

Step-by-step explanation:

1:-

2a^2 - 18a - 72 =

2a^2 - 24a + 6a - 72

2a ( a - 12) + 6 ( a - 12)

(2a + 6) (a - 12)

2:-

x^2y - 3xy -4 =

x^2y -4xy + 1x - 4

xy ( x-4) +1 (x-4)

(xy+1) (x-4)

3:-

m^3 - m^2 - 25m + 25 =

m ( m^2 - m) -25m + 25

m ( m^2 - 26m + 25)

m m^2 - 25m -1m + 25

m m(m-25) -1 (m-25)

(m^2 - 1) ( m-25)

4:-

ax + ay + bx + by =

a(x+y) +b (x + y)

(a+b) (x+y)
