Question 205000


1.	Simplify: 4[a – b(2 + 3a)] – 3a[2+b(4 – a)] 

4[a - b(2 + 3a)] - 3a[2 + b(4 - a)]


Remove the parentheses by distributing. This gives us:


4[a - 2b - 3ab] - 3a[2 + 4b - ab]


{{{4a - 8b - 12ab - 6a - 12ab + 3a^2b}}}


Combine like terms: {{{highlight_green(-2a - 8b - 24ab + 3a^2b)}}}



2.	Simplify: (7x2 –  2y + z) + (3y –  z) + (4x2 – 6y) 

{{{(7x^2 - 2y + z) + (3y - z) + (4x^2 - 6y)}}}

Remove parentheses:  {{{7x^2 - 2y + z + 3y - z + 4x^2 - 6y}}}

Combine like terms: {{{highlight_green(11x^2 - 5y)}}}
