Best ResponseYou've already chosen the best response.1On the first part you are asked to use the discriminant to describe the solutions of the quadratic equation. As you might know, a quadratic equation can be solved using the general formula or "bhaskara's formula": \[x=\frac{ b \pm \sqrt{b^24ac} }{ 2a }\] But this formula has a part we call "discriminant" and as you might have guessed, it is everything inside the radical, the discriminant is often notated with the capital greek letter "delta"; \[\Delta = b^2  4ac\] The discriminant gives away the behavior of the solution of a quadratic equation, therefore, there are 3 possible scenarios: \[1) \Delta >0\] If the discriminant is greater than zero, meaning, a positive number, the quadratic equation will have two solutions x1, x2. \[2) \Delta =0 \] If the discriminant is equal to zero, then the quadratic equation will have one solution and graphically means that the parabola formed is tangent to the xaxis. \[3) \Delta <0\] if the discriminant is negative, the quadratic equation will have no real solutions and graphically means that the parabola formed does not cut the xaxis.

Best ResponseYou've already chosen the best response.1Well, you can use the general formula to solve one, and use factoriation to solve the other.
