Question 887425
Find the product
(x – y)(x² + 2xy – y²)
= {{{x*(x^2 + 2xy - y^2) - y*(x^2 + 2xy - y^2)}}}
= {{{x^3 + 2x^2y - xy^2 - x^2y - 2xy^2 + y^3}}}
= {{{x^3 + x^2y - 3xy^2 + y^3}}}
============
Do these the same way.
Use ^ for exponents, not the superscripts.
-----
(3x – 2)(2x² + 3x – 1)
(x³ + 3x² + 1)(3x² + 6x – 2)
(x² + 9x + 7)(3x² + 9x + 5)
