Question 4 of 10Select the two values of x that are roots of this equation.x2 – 5x + 3 = 0OA. x=5+4675 37X=2B. X=5- 3725 - 13C. X =2<-5-

Answer 1

The roots are C and D.

EXPLANATION :

From the problem, we have :

`x^2-5x+3=0`

Using quadratic formula with a = 1, b = -5 and c = 3

`\begin{gathered} x=(-b\pm√(b^2-4ac))/(2a) \\ \\ x=(-(-5)\pm√((-5)^2-4(1)(3)))/(2(1)) \\ \\ x=(5\pm√(25-12))/(2) \\ \\ x=(5\pm√(13))/(2) \end{gathered}`
