Expression

2*x/(3*x^2-22*x+7)+3/(x^2-5*x-14)

  1. A sum containing 2 terms; the first term of the sum is equal to a rational expression: the numerator of the rational expression is a product containing 2 factors; the first factor of the product is equal to two; the second factor of the product is equal to x; the denominator of the rational expression is a sum of 3 terms; the first term of the sum is equal to a product that consists of 2 factors; the first factor of the product is equal to three; the second factor of the product is a power; the base is x; the exponent is two; the second term of the sum is equal to a negative product that contains 2 factors; the first factor of the product is twenty two; the second factor of the product is equal to x; the third term of the sum is equal to seven; the second term of the sum is equal to a fraction: the top of the fraction is three; the bottom of the fraction is a sum that contains 3 terms; the first term of the sum is a power; the base is x; the exponent is two; the second term of the sum is equal to a negative product consisting of 2 factors; the first factor of the product is equal to five; the second factor of the product is x; the third term of the sum is equal to negative fourteen;
  2. two multiplied by x fraction line three times x to the power of two plus negative twenty two times x plus seven plus three divided by x exponentiated by two plus negative five multiplied by x plus negative fourteen;

Result

(2*x^2+13*x-3)/((3*x-1)*(x+2)*(x-7))
