Question

Check whether the given values are solutions of the given equation or not
X2 - 3x + 20 = 0 ; x = -2, 11.​

Answer 1

Answer:

When x=-2

-2×2-3×-2+20=

-4+6+20=-4+26=22

So by taking -2as the value of x,it is not the solution of equation.

When x=11

11×2-3×11+20=

22-33+20=9

so 11 is also not the solution of equation

Answer 2

Answer:

Answer:

When x=-2

-2×2-3×-2+20=

-4+6+20=-4+26=22

So by taking -2as the value of x,it is not the solution of equation.

When x=11

11×2-3×11+20=

22-33+20=9

so 11 is also not the solution of equation
