Question

how to solve this .......................​

Answer 1

Answer:

answer is c

Step-by-step explanation:

ax^2+bx+c=a(x-p)^2

ax^2+bx+c=ax^2+ap^2–2apx

bx+c=ap^2–2apx

Equating the coeff. of x and constt. term.

b=-2ap or p=-b/2a………………..(1)

c=ap^2…………………..(2)

put p= -b/2a. from eq. (1).

c=a.(-b/2a)^2

c=a.b^2/4a^2

c=b^2/4a , or b^2=4ac , Answer
