Change the following mixed expression to a fraction.
which mixed expression
\[2-\left(\begin{matrix}x ^{2}+10xy+7y ^{2} \\ x ^{2}+4xy+4y ^{2}\end{matrix}\right)\]
Here are the instructions. First multiply the 2 by the given denominator. This will put that product and the original numerator as your new numerator. Then you can simplify by subtracting/combining like terms. After you simplify that will be your final answer for the numerator. The denominator will not change.
i can do it myself no need for instructions
and if you knw how to solve it then why ask a question????
i dont know how to solve it, they just gave me the instructions
imagine you are doing this with a simple fraction instead of the expression: so 2 - 6/7 say one approach is to say that is the same as \[2*7/7-6/7\] this allows you to have common denominator in this case '7' so its (2*7 - 6)/7 this can then be simplified more easily that is basically the approach to take Can you do it from there?
so i should try to find a common denominator?
it is a very easy question
??
i dont understand it
can you please help me?
I would do just what you were instructed to do. 2 times the given denominator would be: 2x^2 +8xy+8y^2 combine that with the numerator 2x^2+x^2+8xy+10xy+4y^2+7y^2 combining: 3x^2+18xy+11y^2 all over the common denominator of ----------------- x^2+4xy+4y^2 continue on.....
