ajprincess · Answer

bt the factors of a quadratic are given in this form
(x-a)(x-b)

anonymous · Answer

i could have solved it by completing the square. i could have solved it many ways. by finding coefficients of 6 would make your life a lot harder

ajprincess · Answer

6x^2+5x-1
=6x^2+6x-x-1
=6x(x+1-(x+1)
=(6x-1)(x+1)

anonymous · Answer

Okay, has your teacher ever let you leave an answer like that? You're supposed to solve for x. Always

anonymous · Answer

@emkaye16 do you have to solve for x?

ajprincess · Answer

that's only when u r given a question like this
solve 6x^2+5x-1=0

ajprincess · Answer

@andres07.

anonymous · Answer

you never offended me.

anonymous · Answer

at the moment no. If the question asks to solve for x, you solve for x. to factor, you leave the form x = -1 and 1/6 as  (x + 1)(6x - 1). Both of you are right.
