You can not solve it as there is no equation to solve however to write this in its simplest form you need to have a common denominator of the fractions. We can see that x²-4 could be written as (x-2)(x+2) and therefore know we have to multiply the second part of the expression by (x+2)/(x+2) to get (x²-4) on the bottom. Now we have: (10x+9)/(x²-4)-(3(x+2))/(x²-4) This can also be written as: ((10x+9)-3(x+2))/(x²-4) Now we can expand and simplify to get: (7x+3)/(x²-4)
To simplify the expression [ x 2 − 4 10 x + 9 ] − [ x − 2 3 ] , first find a common denominator. After rewriting and combining, the result is ( x − 2 ) ( x + 2 ) 7 x + 3 . This form is the simplest representation of the original expression.
