Question

Find x intercepts y=(x+3) (6x-2)

Answer 1

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

Explanation:

to find the x- intercepts let y = 0 , that is

(x + 3)(6x - 2) = 0

equate each factor to zero and solve for x

x + 3 = 0 ( subtract 3 from both sides )

x = - 3

6x - 2 = 0 ( add 2 to both sides )

6x = 2 ( divide both sides by 6 )

x =
`(2)/(6)` =
`(1)/(3)`

the x- intercepts are then x = - 2 and x =
`(1)/(3)`
