Answer:
The value of p is +8 or -8
Step-by-step explanation:
If you gave like this
Find the value of p which Quadratic equation 2x²+px+8=0 has equal roots
Solution:-
Given equation is 2x²+px+8=0
On comparing with ax²+bx+c=0
a=2;b=p;c=8
ax²+bx+c=0 has equal roots then it's discriminant must be equal to zero
discriminant (d)=b²-4ac=0
=>p²-(4)(2)(8)=0
=>p²-64=0
=>p²=64
=>p=±√64
=>p=±8
The value of p is +8 or -8
