Question

1
Find the roots of the equation
1/2x²-root 11x +1=0 by using quadratic formula.​

Answer 1

Step-by-step explanation:

D = b2 - 4ac

= (-root11)2 - 4(1/2)1

= 11 - 2

= 9

x = -b + root D

2a

x = -root11 + rootD

2(1/2)

x = -root 11 + 3

Taking '+' sign Taking '-' sign

x = -root 11 + 3 x = -root 11 - 3
