2x^2-kx+25=0 Divide each term of the equation by 2 .x^2-k/2x+(25)/2-0Assume one of the roots is α.Then, the other root is 2α.∵POR=(α)(2α)=(25)/2∴(a^2)/(a^2)=1Substitute ② into ①:When α=5/2,k=6(5/2)=15When α=-5/2,k=6(-5/2)=-15Therefore,...
An example of a quadratic equation is x^2 + 3x + 4 = 0. You can see that the highest exponent is 2. The usefulness of the quadratic formula is seen when we have a quadratic equation that can't be solved by other methods. When other methods fail, the quadratic formula succeeds. Do...
The problem with a=0 is that there is no longer a quadratic term. This makes the function linear. We can make the most basic quadratic function by making b and c BOTH equal zero. This minimizes the number of terms. We are left with: y=ax2 Let's dive into this.For parabolas, we ...

Explain how to find out if a quadratic has a solution. How can you tell if an equation is quadratic? For the quadratic equation 9x^2 - 36x + 36 = 0, describe the solution(s) to the equation in exact form. Write a quadratic equation that does not have...
Explain why the following equation is true. \int_{-\infty}^{\infty}\int_{-\infty}^{\infty} e^-{(x^2+y^2)} dxdy = (\int_{-\infty}^{\infty} e^{-x^2}dx)^2 Explain what it means for a s y s t e m a x = 0 to have infinitely many solut...
This reduces the problem to finite dimensional stochastic differential equation.Previously, the projection method has only been considered for the Hilbert space structure associated with the Hellinger metric. We show through the numerical example of the quadratic sensor that the approach also works well ...
