Question

find the roots of the quadratic equation using formula method x²+3x+1​

Answer 1

Answer:

Quadratic formula is b+-(b2-4ac)/2a.

Step-by-step explanation:

a=1 b=3 c=1

put the value in above formula

x= 3+-[3^2-4(1)(1)]\2(1)

= 3+-(9-4)/2

=3+-(5)/2

x= 3+5/2. x= 3-5/2

x=8/2

x=4. x= -2/2

x=-1
