state the type of roots for a quadratic equation explaining how the discriminant helps you determine the type

Mathematics
1 answer:
Andrej [43]2 years ago
4 0

You could have a Quadratic with 2 distinct solution meaning you have 2 different X intercepts

2 roots means the discriminan is positive in other words

D>0

When the discriminan is 0, D=0 we have exactly one x-intercept.

Discriminan D=0

and finally, if the discriminan were negative

D=0

then there is no solution or root at all.

Hi! I’m stuck on this problem on math! This is 5th grade math. Can anyone help me?
emmasim [6.3K]

Answer:

The answer is 4.2 kilograms of dog food

Step-by-step explanation:

it says that ray feeds his dog 0.12 kilogram of food each day

he needs for 1 month

1 month = 31 days or 30 days

since 1 day food is 0.12 kilograms you'll have to multiply 0.12 with 1 month

i.e; 0.12*31 or 0.12*30

0.12*31=3.72 and 0.12*30=3.6

since we don't have an option we'll have to choose something bigger than this

therefore, the answer is 4.2

Write a quadratic equation with the given roots. Write the equation in the form of ax^2+bx+c=0 where a b and c are integers
Bas_tet [7]

You haven't provided the required roots, but I can tell you how to do this kind of exercises in general.

If the x^2 coefficient is 1, i.e. the equation is written like x^2+bx+c=0, then you can say the following about the coefficients b and c:

  • b is the opposite of the sum of the roots
  • c is the multiplication of the roots.

So, for example, if we want an equation whose roots are 4 and -2, we have:

  • 4+(-2) = 4-2 = 2 \implies b = -2
  • 4 \cdot (-2) = -8 \implies c = -8

So, the equation is x^2-2x-8=0

If your roots are rational, you can work like this: suppose you want an equation with roots 3/4 and 1/2. You have:

  • \dfrac{3}{4}+\dfrac{1}{2} = \dfrac{3}{4}+\dfrac{2}{4} = \dfrac{5}{4} \implies b = -\dfrac{5}{4}
  • \dfrac{3}{4} \cdot \dfrac{1}{2} = \dfrac{3}{8} \implies c = \dfrac{3}{8}

And so the equation is

x^2 - \dfrac{5}{4} + \dfrac{3}{8} = 0

In order to have integer coefficients, you can multiply both sides of the equation by 8:

8x^2 - 10 + 3 = 0
