Use the quadratic formula to solve the equation:6x^2 + 5x -3 = 0

Given the quadratic
equation:


6x^2 + 5x -3 =
0


Then we know that a = 6   b= 5   and  c =
-3


We will use the quadratic formula to find the
roots.


We know that:


x = [ -b
+- sqrt(b^2-4ac)] / 2a


==> x1 = [ -5 +
sqrt(25+4*6*3)]/ 2*6


          = ( -5 + sqrt97) /
12


==> x2= (
-5-sqrt97)/12


Then the roots
are:


x = { (-5+sqrt97)/12  ,  (-5-sqrt97)/12
}

Can (sec x - cosec x) / (tan x - cot x) be simplified further?

Given the expression ( sec x - csec x ) / (tan x - cot x) We need to simplify. We will use trigonometric identities ...
