" (iii) "((x)/(2)-(2)/(5))((2)/(5)-(x)/(2))-x^(2)+2x

Simplify each of the products: ((x)/(2)-(2)/(5))((2)/(5)-(x)/(2))-x^(2)+2x

(x-3)/(5)-2=(2x)/(5)

(2x+5)/((x-1)(x-2))=

(x^((5)/(2))+2x^(-(1)/(2)))/(x^((5)/(2))-x^(-(1)/(2)))x5/2+2x-1/2 Differentiate 5/2-1/2 with respect to x .

Add :5x^(2)-(1)/(3)x+(5)/(2),-(1)/(2)x^(2)+(1)/(2)x-(1)/(3) and -2x^(2)+(1)/(5)x-(1)/(6)

(2x^(2)-1)/((x^(2)+4)(x^(2)-5))

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

The curvature of the function f(x)=x^(2)+2x+1 at x=0 is (a) (2)/(5^("3/2")) (b) (2)/(5^("1/2")) (c) 2/5 (d) (2)/(5^("-3/2"))

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
