Question

Solve 9x2 + 3 = -8x by using the quadratic formula

Answer 1

\(\large 9x^2+3=-8x \) get this into standard from first to identify your a, b, c
\(\large 9x^2+8x+3=0 \) now can you identify a, b, c from the quadratic equation?

Answer 2

\(\large ax^2+bx+c=0 \)

the quadratic formula:
\(\large x=\frac{-b\pm \sqrt{b^2-4ac}}{2a} \)
