Question

6x2 + 28x - 2 = 2x - 10

Answer 1

x=
`(-1)/(3)`

x= -4

Explanation:

`6x^2+28x-2=2x-10`

Subtract 2x - 10 from both sides.

`6x^2+26x+8=0`

`x= ( -(26) +/ √((26)^2-4(6)(8)) )/(2(6))`

x=
`(-26 +/√(676-4(6)(8)) )/(2(6))`

x=
`(-26 +/ √(676-192) )/(2(6))`

x=
`(-26+/√(484) )/(2(6))`

x=
`(-26+/22)/(12)`

x=
`(-26+22)/(12)` = -0.33333333333333 = -1/3

x=
`(-26-22)/(12)`= -4

Answer 2

x = -1/3 or x = -4
