Can someone help me:(?
Decide which part of the quadratic formula tells you whether the quadratic equation can be solved by factoring.
b b2  4ac 2a
Use the part of the quadratic formula that you chose above and find its value given the following quadratic equation:
4x2 + 6x + 2 = 0 (2 points)

Best ResponseYou've already chosen the best response.2The "discriminant" gives this information. It is the square root part of the quadratic formula. \[\sqrt{b^24ac}\]

Best ResponseYou've already chosen the best response.0is that how it should be set up in order

Best ResponseYou've already chosen the best response.2yes but we need to figure out the values using \[\huge~\rm~ax^2+bx+c=0\] That equation can you list just the NUMBERS not the signs of variables

Best ResponseYou've already chosen the best response.2Ok anything ^2 is the a value anything with an "x" is the b value anything with no varible is the c value now list the numbers :)

Best ResponseYou've already chosen the best response.0so b^2 is A, b is B, and C is 2a?

Best ResponseYou've already chosen the best response.2wut? oo wow you really are confused ok lets start from scratch \[\huge~\rm~x=\frac{ b \pm \sqrt{b^24ac} }{ 2a }\] This is the quadratic formula \[\huge~\rm~ax^2+bx+c=0\] This is standered form The discernment is The "discriminant" gives this information. It is the square root part of the quadratic formula. \[\sqrt{b^24ac}\] We need to solve \[\huge~\rm~4x^2 + 6x + 2 = 0\] Notice how it all matches up with the standered form equation? \[\huge~\rm~ax^2+bx+c=0\]

Best ResponseYou've already chosen the best response.0then why do we need just the numbers

Best ResponseYou've already chosen the best response.2We need just the numbers so that we can solve using the discernment

Best ResponseYou've already chosen the best response.2\[\sqrt{b^24ac}\] So now we have our abc values \[\huge~\rm~ \sqrt{6^24(4)(2)}\] Solve that

Best ResponseYou've already chosen the best response.2its ok :) @kinserkara now 2a it would just be x=2
