2/(5w+10 )- 3/(2w-4)
please show me how to work this problem.
I assume this is some sort of combine the fractions, as there is nothing equal to the sentence above.
factor out 1/((5w+10)(2w-4))
1/((5w+10)(2w-4)) * ( 2*(2w-4) - 3(5w+10) )
do the multiplication in the paren..
1/((5w+10)(2w-4)) * (4w-16 - 15w-30)
1/((5w+10)(2w-4)) (-11w - 46)
you could factor a 10 out of the denominator, making
1/(10( w+2)( w-2)) (-11w - 46)
add or subtract as indicated. express your result in simplest form.
2 over 5x+ 10 subtract 3 over 2w - 4 will this help since I didn't make myself clear?
