Question

5x2+3x+1 solve quadratic equation by completing the square method​

Answer 1

Answer:

5x^2 +3x +1

Compare with ax2+bx+c=0

a=5 b=3 c=1

Find D

D =√b^2-4ac

D =√9-20

D =√-11

(this eqn has irrational roots)

x=(-b+-√D)/2a

Substitute and then find value of x

Since D is negative ,this equation has negative roots.
