Answer:
p=-1
Step-by-step explanation:
3x^2+6x-6=0
Add 6 on both sides
3x^2+6x=6
Divide through by 3
x^2+2x=2
Complete the square on the right side
If a quadratic equation is given by
ax^2+bx+c=0
then c=b/2
x^2+2x=2
c=2/2=1
Adding 1 on both sides
x^2+2x+1=2+1
x^2+x+x+1=3
Combining
x(x+1)+1(x+1)=3
(x+1)(x+1)=3
(x+1)^2=3
p=-1
