2009-08-10 · Re: Solving for all real values of X. x^2 - 9x + 9 = 0 is not factorable, so we must use or complete the square. Since b is not even, completing the square is not that simple, involving fractions and all. So use Quadratic Formula....Advanced Math. Solve 4sin^2 x + 4sqrt(2) cos x-6 = 0 for all real values of x. My answer: (pi/4)+2(pi)k, (7pi/4) + 2(pi)k Solve 2cos^2 x-5cosx+2=0 for principal values of x.

- You can put this solution on YOUR website! tan(x)sec(x)-2tan(x)=0 Solving these equations usually starts with using algebra and/or Trig. identities to transform the equation so that you have one or more equations of the form:
- Solve each equation for all values of x in the real number system. If an exact solution does not exist, round your answers to the nearest hundredth.
- keywords: of,real,sup,Solve,radic,cos,values,for,sin,all,Solve 4 sin² x+4√(2) cos x -6 = 0 for all real values of x Related Rewrite the equation y =(x/5) + 6 in standard form..
- For example, given the equationx – 1| > –5, x is all real numbers. The left-hand side of this equation is an absolute value, and an absolute value always represents a positive number (or zero). Because positive numbers (or zero) are always greater than negative numbers, these types of inequalities always have a solution. Any real number that you put into this equation works.
