Question

Simplify into one fraction (6/x+7)-(3/x-2)

Answer 1

6/x +7 -(3/x -2 )

= (9x+3)/x

I hope that's help !

Answer 2

Remove the parentheses: ( a) = a


`(6)/(x+7) - (3)/(x-2)`

Find the least common denominator:


`(x+7)(x-2)`

Adjust fractions based on the LCD :


`(6(x-2))/((x+7)(x-2)) - (3(x+7))/((x+7)(x-2))`


`= (6(x-2)-3(x+7))/((x+7)(x-2))`

Expand :


`6(x-2)-3(x+7)`


`6 x - 12 - 3 x - 21`


`6x - 3 x - 12 - 21`


`3x - 33`


`(3x-33)/((x+7)(x-2))`

hope this helps!
