Question

6. Subtract:
(i) 3l (l - 4m + 5n) from 2l (5n - 2m + l)​

Answer 1

Answer:

-l2-8ml-5ln

Step-by-step explanation:

2l2-4ml+10ln-3l2+12ml-15ln

-l2-8ml-5ln

Answer 2

Step-by-step explanation:

$3l {}^{2} - 12lm + 15ln \: from \: 10ln - 4lm + 2l { }^{2} \\ \\ 10ln - 4lm + 2l {}^{2} - (3l {}^{2} - 12lm + 15ln) \\ \\ 10ln - 4lm + 2l {}^{2} - 3l {}^{2} + 12lm - 15ln \\ \\ - 5ln + 8lm - l {}^{2} \\ - l {}^{2} + 8lm - 5ln$

$- l {}^{2} + 8lm - 5ln$
