    Is my answer right, \[(x-8)(x+\frac{ 17 }{ x-8 })\]

    there's a prime number ... so I highly doubt we can factor without the quadratic formula. that's one strange root...since it's supposed to be all numbers

    solve the equation u got and see it matches with the equation u got

    are you aware of the discriminant formula \[b^2-4ac\]

    I guess so...that's the formula for checking perfect trinomials right?

    Going back, is (x−8)(x+17/x−8) right?

    a = 1 b = -8 c=17

    @JustinSpeedster r u only askd to factorize it or get the values of x???

    Factorize only.

    probably to factor, but how? since 17 is a prime. The only combinations are 1 x 17 17 x 1

    \[(-8)^2-4(1)(17) \] solve this first. do you have a perfect square ?

    It's obviously not a perfect square.

    But if we were to solve this: \[(x+8) (x+\frac{ 17 }{ x+8 }) = x^2 +8x+17\]

    \[64-68 = -4 \] oh nice... we're going to have some imaginary i thing going on .

    both of those aren't the right roots.

    because roots are all numbers. You can't have variables in them

    this equation has complex roots in them

    x+8 distributed to x = x^2 + 8x x+8 distrubted to x+17/x+8 leaves = 17

    you have to use the quadratic formula... wow I keep on typing that you can't have variables in the roots

    missed a sign (x-(4+i))(x-(4-i)) the roots are x = 4+i and x = 4-i respectfully right @rishavraj

    use discriminant formula first then quadratic formula to get the roots finally put it in factorized form ..
