$3x^m\left(3x^m-7y^n\right)+4y^n\left(3x^m-7y^n\right)$
Learn how to solve special products problems step by step online. Solve the product (3x^m+4y^n)(3x^m-7y^n). Multiply the single term 3x^m-7y^n by each term of the polynomial \left(3x^m+4y^n\right). Multiply the single term 3x^m by each term of the polynomial \left(3x^m-7y^n\right). When multiplying two powers that have the same base (x^m), you can add the exponents. Multiply the single term 4y^n by each term of the polynomial \left(3x^m-7y^n\right).
Final Answer
$9x^{2m}-9x^my^n-28y^{2n}$
