Tìm x, biết (5x-3)^2 - (5x+3)^2 = 6
Tìm x biết: (5x-3)^2-(5x+3)^2=6
(2x-3)^2-(x+5)^2=0
x^2-9+(x+3)(3x-5)=0
(2x-1)^2-16=0
(2x-1)^2-(2x)^2=4
x^2(2-x)+9(x-2)=0
(x-1)^2+4(x-1)=-4
(2x+3)^2-2(2x+3)(2x-5)+(2x-5)^2=x^2+6x+64
(2x-3)^2-(x+5)^2=0
x^2-9+(x+3)(3x-5)=0
(2x-1)^2-16=0
(2x-1)^2-(2x)^2=4
x^2(2-x)+9(x-2)=0
(x-1)^2+4(x-1)=-4
(2x+3)^2-2(2x+3)(2x-5)+(2x-5)^2=x^2+6x+64
