Question

Hey there i posted picture of question can you please help

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 = 20
a = coefficient of squared term = 3
c = constant term = -7

Using the values, we get:


`x= (-20+- √(400-4(3)(-7)) )/(2(3)) \\ \\ x= (-20+- 22 )/(6) \\ \\ x=-7 , x= (1)/(3)`

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