Question

factor 3x^2-7x-7

Answer 1

Kinda gnarly to factor... are you familiar with the quadratic formula?

\(x=\dfrac{-b\pm\sqrt{b^2-4ac}}{2a}\)
for
\(ax^2+bx+c=0\)

Answer 2

i got 7 +- sqrt. of -35/ 6

Answer 3

but that doesnt sound right

Answer 4

\(x=\dfrac{-(-7)\pm\sqrt{(-7)^2-4(3)(-7)}}{2(3)}=\dfrac{7\pm\sqrt{133}}{6}\)

So for our two answers we have,

\(x=\dfrac{7+\sqrt{133}}{6}\)

AND

\(x=\dfrac{7-\sqrt{133}}{6}\)

Answer 5

oh okay got you
