Best ResponseYou've already chosen the best response.0 The value of the discriminant is 169. There are 2 real roots. There are 2 irrational roots. The graph intersects the yaxis twice. The parabola is directed upward. The axis of symmetry is located at The vertex is located at: The roots are: The graph intersects the y axis at (0, 15). The graph intersects the xaxis at (5, 0) and (1.5, 0) II. Use the quadratic formula to solve the following:

Best ResponseYou've already chosen the best response.0\[\huge\rm 2x^2+7x15=0\] quadratic equation ax^2+bx+c quadratic equation where a=leading coefficient b=middle term cconstant term so what is a b and c in that equation ? \[\huge\rm x=\frac{ b \pm \sqrt{b^24ac} }{ 2a }\]quadratic formula

Best ResponseYou've already chosen the best response.0\(\huge\color{reD}{\rm b^24ac}\) `Discriminant` you can use this to find if the equation is factorable or not if ` b^24ac > 0` then there are 2 real zeros if ` b^24ac = 0` then there is one real root if ` b^24ac < 0` then you will get two complex roots (no xintercept)

Best ResponseYou've already chosen the best response.0Ax^2+Bx+C standard form equation of parabola where a = leading coefficient b= middle term c=constant term now look at this equation 2x^2+7x15 what is a b and c ?

Best ResponseYou've already chosen the best response.0alright \[\huge\rm b^24ac\] substitute b a and c values then sovle

Best ResponseYou've already chosen the best response.0just replace b with 7 a with 2 c with 15

Best ResponseYou've already chosen the best response.0here is how i would replace b with 7...... \[\rm (7)^24ac\] ur turn replace a with 2 and c with 15

Best ResponseYou've already chosen the best response.0that's not an answer you don't know or you don't want to do it ? you can use calculator just put 498(15) into the calculator that's it

Best ResponseYou've already chosen the best response.0yes right 49+120 = ? that would be discriminant

Best ResponseYou've already chosen the best response.0yes right so first sentence is right ? ` The value of the discriminant is 169`
