Question

factorise the 8m^3-2m^2n-15mn^2​

Answer 1

Answer:

8m³-2m²n-15mn²

• 8×15=120

=>8m³-12m²n+10m²n-15mn²

=>4m²(2m-3n)+5mn(2m-3n)

=>(4m²+5mn)(2m-3n)

i hope this will help u

Answer 2

Step-by-step explanation:

given algebraic number is

8m³ - 2m²n - 15 mn²

to factorise it we will choose two numbers which give 2 when added and give 120 when multiplied

15×8 = 120

12×10=120 and 12-10=2

so now

8m³ - 12m²n + 10m²n - 15mn²

4m²( 2m - 3n ) + 5mn( 2m - 3n )

(4m² + 5mn)(2m - 3n)

it is our answer
