Answer:hope it helps u out , plsz bring to my notice if u don't u . I will be glad to clear .

Step-by-step explanation:

Answer 2

Here is your answer....

P - 15 = 0

From the above equation

P = 15

so,

now,

2x^2 + Px + 25 = 0

put value of P

2x^2 + 15x + 25 = 0

then by splitting the middle term

2x^2 + 10x + 5x + 25 = 0

2x(x + 5) + 5(x + 5) = 0

(x + 5) (2x + 5) = 0

so...

x + 5 = 0 or 2x + 5 = 0

x = -5 or x = -5/2
