Answer 2

Step-by-step explanation:

simplify the expressions

$1.4ab + ( - 5ab) + ( - 3ab) \\ = 4ab - 5ab + ( - 3b) \\ = 4ab - 5ab - 3b \\ = - ab - 3b$

$2.6xy {}^{2} + ( - 8xy {}^{2} ) + ( - 3xy {}^{2} ) \\ = 6xy { }^{2} - 8xy {}^{2} + ( - 3xy {}^{2} ) \\ = 6xy {}^{2} - 8xy {}^{2} - 3xy {}^{2} \\ = - 5xy {}^{2}$
