an ordered pair that satisfies an equation in two variables is called its solution. a) root . b) solution.pls explain how its called root?
Answer :
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 : x2 + 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 .
