<u><em>The LCM of 156 and 321 is 16692</em></u>
Backup:
156: 2,2,3,13,
321: 3,107
2 * 2 * 3 * 13 * 107 = 16692
:)
The answer will be 100,000 be3cause 6+4 is 10 and add 4 zero's
(7x - 2y) (3x +5y) ( First open brackets)
= 21x² + 35xy - 6xy - 10y² ( solve like terms)
= 21 x² - 10y² + 29xy.
1512 is the answer
