## anonymous one year ago A quadratic equation is shown below: 9x2 − 16x + 60 = 0 Part A: Describe the solution(s) to the equation by just determining the radicand. Show your work Part B: Solve 4x2 + 8x − 5 = 0 by using an appropriate method. Show the steps of your work, and explain why you chose the method used.

Get the app "mathway "it will give you an answer

4. anonymous

Will it help me learn it just a tad? I barley understand these things

5. anonymous

No it will just give you the right answer you have to pay to get an explanation sorry

6. anonymous

Thank you anyways!

radicand= discriminant what's the qudratic formula ?

yes rigght $$\huge\color{reD}{\rm b^2-4ac}$$ Discriminant you can use this to find if the equation is factorable or not if  b^2-4ac > 0 then there are 2 real zeros if  b^2-4ac = 0 then there is one real root if  b^2-4ac < 0 then you will get two complex roots (no -x-intercept)

thats for part A^

Oh, okay, thank you, and now to part B, do I use the quadratic formula again?

14. Nnesha

yes right !

15. Nnesha

substitute a b ,c then solve
