given algebraic expression are : 4a² + 5b² + 6ab , 3ab , 6a² - 2b² , 4b² - 5ab;
now adding all expressions ;[horizontal method ]
= (4a² + 5b² + 6ab) + 3ab + ( 6a² - 2b² ) + (4b² - 5ab)
= (4a² + 6a² ) + (5b² - 2b² + 4b² ) + (6ab + 3ab - 5ab)
= 10a² + 7b² + 4ab
add all expressions [vertical method ]
4a² + 5b² + 6ab
+ 3ab
+6a² - 2b²
+ 4b² - 5ab
