how do you get the product of the sum and the difference of two terms?

Sagot :

Sundin nyo lang po ang formula ito :
(a+b)(a-b) = [tex] a^{2} - b^{2} [/tex]

ex.
(3x +4)(3x-4) = [tex] 9x^{2} - 16[/tex]
Basta po laging negative yung second term or you can use the foil method po or the tuktok system.
