Question

Someone please help me with this

Answer 1

3/2 and -2

Explanation:

The quadratic formula is
`x=(-b+/-√(b^2-4ac) )/(2a)`. Here a=2, b=1, and c=-6.

Substitute and you'll have:

`x=(-b+/-√(b^2-4ac) )/(2a) =(-1+/-√(1^2-4(2)(-6)) )/(2(2))=(-1+/-√(1+48) )/(4))`

`(-1+/-√(1+48) )/(4)=(-1+/-√(49) )/(4)=(-1+/-7 )/(4)= (3)/(2) , -2`
