(a+b)²=a²+2ab+b²
(2x+2)^2= 4x²+8x+4
(a-b)²= a²-2ab+b²
(x-1)^2= x²-2x+1
(3x-2)^2=9x²-12x+4
(a-b)*(a+b) = a²- b²
(a-3)(a+3) = a²-9
(x-5)(x+5)=x²-25
(2x-3)(2x+3)=4x²-9
(7x-2y)(7x+2y)=49x²-4y²
Wzory skróconego mnożenia:
(a+b)^2=a^2+2ab+b^2
(a-b)^2=a^2-2ab+b^2
(a+b)(a-b)=a^2-b^2
(2x+2)^2=4x^2+8x+4
(x-1)^2=x^2-2x+1
(3x-2)^2=9x^2-12x+4
(a-3)(a+3)=a^2-9
(x-5)(x+5)=x^2-25
(2x-3)(2x+3)=4x^2-9
(7x-2y)(7x+2y)=49x^2-4y^2
