Command

Factor

Expression

a*b+a*c+(-4)*b+(-4)*c

  1. A sum containing 4 terms. The 1st term of the sum is equal to a product comprising 2 factors. The 1st factor of the product is equal to a. The 2nd factor of the product is equal to b. The 2nd term of the sum is equal to a product comprising 2 factors. The 1st factor of the product is equal to a. The 2nd factor of the product is equal to c. The 3rd term of the sum is a product containing 2 factors. The 1st factor of the product is equal to negative four. The 2nd factor of the product is equal to b. The 4th term of the sum is equal to a product that comprises 2 factors. The 1st factor of the product is negative four. The 2nd factor of the product is c.
  2. a times b plus a times c plus opening bracket negative four closing bracket times b plus open bracket negative four close bracket times c;

Result

(a-4)*(c+b)
