Beta-blockers, alpha2-adrenergic agonists, and thiazide diuretics are associated with libido changes. Testosterone is the main hormonal mediator of a manâs libido. As testosterone levels decline, sexual desire decreases; therefore medications that affect testosterone can alter the libido. Finasteride and dutasteride, 5-alpha reductase inhibitors for the treatment of benign prostate hyperplasia (BPH), decrease dihydrotestosterone levels, the active metabolite of testosterone.
Solving an equation symbolically means that expressions that may contain known variables or possibly also variables not in the original equation are admitted as solutions. For example, the equation x + y = 2x â 1 is solved for the unknown x by the solution x = y + 1, because substituting y + 1 for x in the equation results in (y + 1) + y = 2(y + 1) â 1, a true statement.
Solve for x. Solution. Even though this equation can be solved by simpler means, we are looking at using the complete the square formula, so add 1 to both sides and put in a ghost or zero term to hold the x place: Now that the equation is in standard form, we have b = 0, b/2 = 0 and k = 1.Plugging these values into the equation yields.his equation is then factored in a straightforward way, and the solutions are found by simply taking the square root of both sides: Clearly these would be difficult to find by guessing. Also, note that there is a +/- symbol, indicating that there are two roots, one using the + sign and the other using the  sign.
