use the quadratic formula

anonymous · Answer

i wanna make sure i did it correct

anonymous · Answer

plug and chug.
$$x=\frac{-b\pm\sqrt{b^2-4ac}}{2a}$$

anonymous · Answer

ok we get 
a = 10
b = 2
c = -3

anonymous · Answer

best to write them down and then you know what you are substituting

anonymous · Answer

less likely to screw up

anonymous · Answer

What is the answer you got? We can tell you if its right or not, This is the 5th one of these ive seen from you :P maybe we can teach you instead of give answers. Again, it is in standard form of $$ax^2 + bx + c = 0$$ now, just plug and chug into the quadratic equation :)

anonymous · Answer

$$\frac{-2\pm\sqrt{2^2-4\times 10\times -3}}{2\times 10}$$

anonymous · Answer

ok so -2+- square root 2^2-4(2)(-3)/2(10)

anonymous · Answer

i get 
$$\frac{-1\pm\sqrt{31}}{10}$$

anonymous · Answer

oh wait i am sorry you are right

anonymous · Answer

you are correct.

anonymous · Answer

$$-2\pm \sqrt{28}$$/20

anonymous · Answer

get 
$$\frac{-2\pm\sqrt{124}}{20}$$

anonymous · Answer

think you messed up with 
$$b^2-4ac$$ again

anonymous · Answer

$$2^2-4\times 10\times -3$$ two minus signs so it is plus

anonymous · Answer

$$4+120$$

anonymous · Answer

124

anonymous · Answer

-2 +- square root 124/20
