Command

Factor

Expression

x^2+7/2*x-7/4

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

Result

(4*x^2+14*x-7)/4

  1. A rational expression: the numerator of the rational expression is a sum that contains 3 terms. The first term of the sum is equal to a product comprising 2 factors. The first factor of the product is equal to four. The second factor of the product is equal to a power. The base is x. The exponent is two. The second term of the sum is equal to a product comprising 2 factors. The first factor of the product is fourteen. The second factor of the product is equal to x. The third term of the sum is negative seven. The denominator of the rational expression is four.
  2. four multiplied by x to the power of two plus fourteen multiplied by x plus negative seven divided by four;
