put x=3 in the equation
then
2x^2-3x+p=0
2×(3)^2-3×3+p=0
2×9-9+p=0
18-9+p=0
9+p=0
p= -9
This is the correct answer
then
2x^2-3x+p=0
2×(3)^2-3×3+p=0
2×9-9+p=0
18-9+p=0
9+p=0
p= -9
This is the correct answer
Alanaaron:
And other root
in the place of x you will try any numbers
when answer is coming 0 that is the another root
ok
