anonymous · Answer

b^2 - 4ac is the correct term for factoring. Can you solve the rest?

anonymous · Answer

I get to 7/25
            4

anonymous · Answer

then i dont know what next

hartnn · Answer

Compare your quadratic equation$ 2x^2 + 7x + 3 = 0 $
with $ax^2+bx+c=0$
find $$a=...?\b=...?\c=...?\$$

anonymous · Answer

I get all that part i put in everything right i just get stuck at
7/25
     4

hartnn · Answer

whats that ?
tell me what a,b,c values u got ?

anonymous · Answer

A=2
B=7
C=3

hartnn · Answer

ohh, you mean you got b^2 -4ac = 25 
right ? 
thats it!
value of b^2-4ac was asked!

anonymous · Answer

$$7\sqrt{25}/4$$
this is how far i get but the four is on the bottom

hartnn · Answer

and since it is a perfect square, the equation can be solved by factoring :)

anonymous · Answer

ohhh that what iam doing wroung i was using quadric equation thank you again
