Answer:
Option D
Step-by-step explanation:
Verify each quadratic equation
case A) we have
This quadratic equation has a leading coefficient of 1
Substitute the value of x=3 and x=-2 in the equation
For x=3
----> is not true
therefore
x=3 is not a solution of the quadratic equation
case B) we have
This quadratic equation has a leading coefficient of 1
Substitute the value of x=3 and x=-2 in the equation
For x=3
----> is not true
therefore
x=3 is not a solution of the quadratic equation
case C) we have
This quadratic equation has a leading coefficient of 1
Substitute the value of x=3 and x=-2 in the equation
For x=3
----> is not true
therefore
x=3 is not a solution of the quadratic equation
case D) we have
This quadratic equation has a leading coefficient of 1
Substitute the value of x=3 and x=-2 in the equation
For x=3
----> is true
therefore
x=3 is a solution of the quadratic equation
For x=-2
----> is true
therefore
x=-2 is a solution of the quadratic equation
