Answer

4x2−12xy+9y24x^2 - 12xy + 9y^2

Step-by-step solution

4 steps

Here's how to expand and simplify the expression:

  1. Write the expression as a product of two binomials.

    (2x−3y)2=(2x−3y)(2x−3y)(2x - 3y)^2 = (2x - 3y)(2x - 3y)
  2. Distribute each term from the first binomial to the second binomial.

    =2x(2x−3y)−3y(2x−3y)= 2x(2x - 3y) - 3y(2x - 3y)
  3. Multiply the terms.

    =(2x)(2x)+(2x)(−3y)+(−3y)(2x)+(−3y)(−3y)= (2x)(2x) + (2x)(-3y) + (-3y)(2x) + (-3y)(-3y) =4x2−6xy−6xy+9y2= 4x^2 - 6xy - 6xy + 9y^2
  4. Combine the like terms.

    =4x2−12xy+9y2= 4x^2 - 12xy + 9y^2

    The final answer is 4x2−12xy+9y24x^2 - 12xy + 9y^2.
