I have a problem where I am to find the intersection between the two curves $$ \begin{cases} x^2 - y^2 = 3 \\ xy = 2, \end{cases} $$ which I can easily see that the two points $\pm(2,1)$ are the real solutions to this problem, but I don't know how to solve for this systematically. I tried two approaches to solve for it as a quadratic equation formula and always convert the system of equations to that form Reducible Equations (i) Often students write answer in terms of substituted variables In the questions based on equations reducible to linear form like 2 3 + =2 x y - (1) 4 9 − =−1 x y - (2) Let 1 =A x and 1 =B y Solving 2A+3B =2 And 4A -9B = -1 Gives A= ½ and B = 1/3 bu In real life, problems are much more complex. The equations are often not reducible to a single variable (hence multi--variable calculus is needed) and the equations themselves may be difficult to form. Understanding the principles here will provide a good foundation for the mathematics you will likely encounter later We know that the time at which the balls pass each other must be at least 3 because the second ball is not thrown until t=3. Therefore, the first solution is invalid, and thus t=23.626 sec. Putting the value of t into the second equation (also set it equal to 100 like before). 100=+v (23.626−3) −4.9 (23.626−3)^2

Solution: The discriminant D of the given equation is. D = b 2 - 4ac. = (-4) 2 - (4 x 4 x 1) = 16-16=0. Clearly, the discriminant of the given quadratic equation is zero. Therefore, the roots are real and equal. Hence, here we have understood the nature of roots very clearly Based on that, the piecewise linear control law is applied to the original problem, and in Fig. 5, the value of the quadratic constraint is plotted. As expected, the nonlinear optimal control law is feasible and satisfies the quadratic constraint and updating X:= X 0 + δX.In certain situations, the correction admits approximate low-rank solutions that can be computed in a relatively inexpensive manner.Previous work [] has shown this to be the case for large-scale Sylvester equations, resulting in a divide-and-conquer method based on such low-rank updates.In this work, we extend these developments to two types of quadratic matrix.
