Find the value of the discriminant for each quadratic equation below. Show all steps needed to write the answer in simplest form, including substituting the values of a, b, and c in the discriminant formula. Then use the value to determine how many real number solutions each equation has. 2x^2 -3x = -5

hi

do you know the "standard form" of quadratic equation ?
Diana.xL
  • Diana.xL
2x^2 -3x = -5 would my equation be 2x^2 -3x +5 = 0?
ganeshie8
  • ganeshie8
Exactly!

Did you solve it out like they asked you to? I honestly forgot how to do this work because I'm now a sophomore in high school so...

  • ganeshie8
compare that with \(\color{red}{a}x^2 + \color{red}{b}x +\color{red}{c}=0\)
ganeshie8
  • ganeshie8
\(\color{red}{a}=?\) \(\color{red}{b}=?\) \(\color{red}{c}=?\)

Oh wait, never mind! You've got your answer. Never mind, you're on the right track. Carry on.

a = 2, b = -3, c = 5

Very good! next find the discriminant using the definition : discriminant = \(b^2-4ac\)
ganeshie8
  • ganeshie8
simply plugin the values and simplify

D = -3 – 4 (2)(5)

*applauding*
ganeshie8
  • ganeshie8
D = (-3)^2 – 4 (2)(5)

oh ok. would my final answer be -31?
ganeshie8
  • ganeshie8
Yes, so the discriminant is \(-31\), which is negative. so how many real solution the given quadratic equation will be having ?
Diana.xL
  • Diana.xL
Since D is negative, root (D) doesn’t exist so the roots are unreal.
ganeshie8
  • ganeshie8
Awesome! so there are no real roots for the given quadratic equation

Okay so let me get this straight: So the asking person is asking this very confusing question which I DO NOT GET ANYMORE!!!! (Sorry for all caps). Ah... could someone teach me this stuff again? I know the powers pretty well but this particular problem like this. It's not like it's for homework anything but I really need help understanding this. I'm learning Geometry this year and I really just need some math help right now. Thanks!
