(2x+5)^(2)-(2x-5)^(2)

((5x+2)^(2)+(5x-2)^(2))/((5x+2)^(2)-(5x-2)^(2))=(13)/(12) then find x

Simplify: (3x+5)^2 - (2x-5)^2

The value of the determinant |{:(1 ,(5^(2x)-5^(-2x))^(2),(5^(2x)-5^(-2x))^(2)),(1 ,(6^(2x)-6^(-2x))^(2),(6^(2x)-6^(-2x))^(2)),(1 ,(7^(2x)-7^(-2x))^(2),(7^(2x)-7^(-2x))^(2)):}| is

Solve: (x^(2)-2x+5)/(3x^(2)-2x-5)>(1)/(2)
