Formula for quadratics would be:
$$ax^2+bx+c$$

anonymous · Answer

oops sorry the equation is 3x^2 - 16x + 2 = 0

yanasidlinskiy · Answer

Can you post it up again? Because you have different equations..In the parts^

anonymous · Answer

In the equation: $ax^2+bx+c=0$'

$discriminant\ (D)=b^2-4ac$, 

to solve for the zeroes/solutions, you can use the quadratic formula $\Large x = \frac {-b \pm \sqrt {b^2 - 4ac}}{2a}$
