# an ordered pair that satisfies an equation in two variables is called its solution. a) root . b) solution.pls explain how its called root?

When our equation is linear equation then the pair of value satisfied the equation is called the solution of this equation , As :

*x*+

*y*= 5

And value ( 2 , 3 ) So

2 + 3 = 5

5 = 5 ( Satisfied )

So , This pair is a solution of this equation .

And when we have have quardetic equation , than the value that makes our equation is zero is called zeros .

and roots are basically the factors of this equation , As :

*x*

^{2}+ 5

*x +*6 = 0

Here ( - 2 , -3 ) are two zeros as both makes our equation is equal to zeros , as

(- 2 )

^{2}+ 5 ( - 2 ) + 6 = 0

4 - 10 + 6

0 = 0

And

(- 3 )

^{2}+ 5 ( - 3 ) + 6 = 0

9 - 15 + 6

0 = 0

And (

*x*+ 2 ) And (

*x*+ 3 ) are two roots of this equation .
