Just multiply the value by the numerator of the fraction.
So what would:
Just FOIL it out as you normally would.
I have an expression;
(1 - u)(2u + 1/3) I am asked to multiply out the brackets and simplify. I am concerned about the fraction because I cannot find any examples in my course book to help with this type of expression.
am I doing it correctly by this method;
(1 - u)(2u + 1/3) = 2u + 3 - 2u^2 - 3u
That's right. FOIL is a general approach to quadratics; multiply the:
...terms together. You don't have to use it to expand if you prefer not to. The method you used in the original post is fine except for a very minor error when taking the fraction into account.
