the way to simplify a product of 3 factors; 3*e*5*x2*e*7 | study easy methods to multiply out a sum consisting of 3 terms; (x-6)*(x-7)

Command

Expand

Expression

(X+Y)*(X-Y)

  1. A product of 2 factors. The first factor of the product is a sum containing 2 terms. The first term of the sum is equal to X. The second term of the sum is equal to Y. The second factor of the product is equal to a sum consisting of 2 terms. The first term of the sum is equal to X. The second term of the sum is equal to negative Y.
  2. open bracket X plus Y close bracket multiplied by open parenthesis X plus negative Y close parenthesis;

Result

X^2-Y^2

  1. A sum containing 2 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 power; the base is Y; the exponent is two;
  2. X exponentiated by two plus negative Y raised to the power two ;
