Question

remove the parenthesis and simplify 3a+5b-8(5a-7b)

Answer 1

\[3a+5b-8(5a-7b)\]
To get rid of the parentheses, we need to use distributive property. So,
\[-8\times5a=-40a\]
\[-8\times -7b=56b\]
Which turns the original expression into;
\[3a+5b-40a+56b\]
And now all that's left is to combine like terms
\[3a-40a=-37a\]
\[5b+56b=61b\]
So that forms;
\[-37a+61b\]
