Factorise it!
Draw the graph of the equation. the solution is/are the points where the line cuts the x(horisontal) axis .
dun know :D
Quadratic equations like this one usually have two solution. Sometimes they have one (so-called "double") solution. If you solve it, you'll know for sure.
we study linear equation in other to know more about quadratic equation
If the equation is an identity.

They will be on the horizontal x axis of the graph (look for the x-intercepts).
You know an equation is quadratic by looking at the degree of the highest power in the equation. If it is 2, then it is quadratic. so any equation or polynomial of the form: ax2 +bx+c=0 where a is NOT 0 and a, b and c are known as the quadratic coefficients is a quadratic equation.
Write the quadratic equation in the standard form: ax2 + bx + c = 0 Then calculate the discriminant = b2 - 4ac If the discriminant is greater than zero, there are two distinct real solutions. If the discriminant is zero, there is one real solution. If the discriminany is less than zero, there are no real solutions (there will be two distinct imaginary solutions).

i dont know 8x+5y=89
If you know how to complete the square, this link will finish the job for you. http://www.mathsisfun.com/algebra/quadratic-equation-derivation.html
The answer depends on what the factors will be. For example, every quadratic can be factored if you allow complex numbers. If not, then it helps to use the discriminant. If it is positive, there are two real factors or solutions. If that positive number is a perfect square, then the factors are rational numbers. If not, they are real but not rational (irrational). If the discriminant is 0, there is one real solution. Lastly, if it is negative, there are no real solutions.
i do not know hahahahahahahaha lol :)
