Question

What are the roots of the quadratic equation below?
2x2 - 12x + 13 = 0

Answer 1

D

Explanation:

Quadratic formula:
`(-b+-√(b^2-4ac) )/(2a)`

`2x^2- 12x + 13 = 0`

`x=(-(-12)+-√((-12)^2-4(2)(13)) )/(2(2))`

`x=(12+-√(144-104) )/(4)`

`x=(12+-√(40) )/(4)`

`x=(12+-2√(10))/(4)`

`x=(6+-√(10))/(2)`

I hope this helps!
