## anonymous 5 years ago 2x2 + 9x + 4 = 0 solve by using the quadratic formula.

1. anonymous

$ax^2+bx+c=0\implies x=\frac{-b\pm \sqrt{b^2-4ac}}{2a}$Work it out for yourself.

2. anonymous

just substitute a,b and c into the eqn provided by bendt... here a=2 b=9 c=4

and verify the results by factoring.
