Question

10. For what vlaue of p does the quadratic equation 25x2+10px+9=0 have equal roots​

Answer 1

Answer:

p = 3 hope it helps

Step-by-step explanation:

$25x^{2} +10px + 9 =0\\\\(5x)^{2} + 10px + 3^{2} = 0\\Comparing with\\a^{2} +2ab+ b^{2}$

a here is 5x

b here is 3

So, comparing with middle term

2ab=10px

Putting value of a and b

2(5x)(3) = 10px

30x = 10px

30x/10x=p

P = 3
