If you mean: x+y = 8 and -x+2y = 7, then they are simultaneous equations whose solutions are x = 3 and y = 5.
The collocation method for solving second-order differential equations involves transforming the differential equation into a system of algebraic equations by selecting a set of discrete points (collocation points) within the domain. The solution is approximated using a linear combination of basis functions, typically polynomial, and the coefficients are determined by enforcing the differential equation at the chosen collocation points. This approach allows for greater flexibility in handling complex boundary conditions and non-linear problems. The resulting system is then solved using numerical techniques to obtain an approximate solution to the original differential equation.
x(x - 1)(4x - 15)
get a life and hobbies then this question wont even be relevent
The equation is -x2 - 4 = 14 or -x2 = 18 which is the same as x2 = -18. That is the quadratic equation.
You'd need another equation to sub in
solve system equation using addition method 3x-y=9 2x+y=6
you cant
For a linear I can see no advantage in the table method.

Start with a quadratic equation in the form � � 2 � � � = 0 ax 2 +bx+c=0, where � a, � b, and � c are constants, and � a is not equal to zero ( � ≠ 0 a =0).
In numerical analysis finding the roots of an equation requires taking an equation set to 0 and using iteration techniques to get a value for x that solves the equation. The best method to find roots of polynomials is the Newton-Raphson method, please look at the related question for how it works.
