Question

26. If both the zeros of the polynomial x2+2px+4p+5 are equal, find the value of p​

Answer 1

if it has equal zeroes then it says that b^2-4ac (discriminant) is equal to be 0

2.here, a=1 , b=2p and c=5

Step-by-step explanation:

3.b^2-4ac=2p^2-4(1)(5)=0

4.=4p^2-20=0

5.=p^2=20/4

6.p=√5
