Hey can you please help me posted picture of question

Answer 1

We can use quadratic formula to determine the roots of the given quadratic equation.

The quadratic formula is:


`x= \frac{-b+- \sqrt{ b^(2) -4ac} }{2a}`

b = coefficient of x term = -11
a = coefficient of squared term = 2
c = constant term = 15

Using the values, we get:

`x= (11+- √(121-4(2)(15)) )/(2(2)) \\ \\ x= (11+-1)/(4) \\ \\ x=3, x= 2.5`

So, the correct answer to this question are option B and D
