Question

what is the value of x
-3x^2+18x-24=0

Answer 1

do you know factoring or the quadratic formula ? which method you wanna use?

Answer 2

quadratic formula

Answer 3

ok... let's make things easier so we can work with smaller numbers..

dividing both sides by -3 we should get:

x^2 - 6x + 8 = 0

can you identify a, b, c ?

Answer 4

\[\begin{array}{*{20}c} {x = \frac{{ - b \pm \sqrt {b^2 - 4ac} }}{{2a}}} & {{\rm{when}}} & {ax^2 + bx + c = 0} \\ \end{array}\]

Your equation gives us:

\[x^2-6x+8=0\]
