Ohhh... I get it now! Since the question didn't mention the type of Roots that the equation possesses [Real Distinct Roots, Equal Roots, Unreal Roots], I won't be able to solve Line 5. Line 1: 2(\alpha)2 = 2 Line 2: (\alpha)2 = 1 Line 3: (\alpha)2 - 1 = 0 Line 4: (\alpha + 1)(\alpha...

Homework Statement Solve the equation ax2 + bx + c = 0. The following are the given information: (a) a = 1 (b) One root is twice the other root. (c) c = 2 You are NOT required to solve the problem but to decide whether: 1) The given information is all needed to solve the problem. In...

Ohhhhh... now i get it! :smile: Since the question has already informed us that x is real for the following formula: x = \frac{-b + \sqrt{b^{2} - 4ac}}{2a} therefore, (b2 - 4ac) can either be equal or greater than zero, so as to produce real roots for this quadratic equation...

Homework Statement If x is real and p = \frac{3(x^{2}+1)}{2x-1}, prove that p2 - 3(p+3) \geq 0. Homework Equations ax2 + bx + c = 0 x = \frac{-b \pm \sqrt{b^{2}-4ac}}{2a} Nature of the Roots of a Quadratic Equation: If b2 - 4ac is positive, quadratic equation has two real &...
