<u>ANSWER: </u>
If x =
and x = -3 are the roots of the equation, then values of a and b are 3, -6
<u>SOLUTION:
</u>
Given, quadratic equation is
and its roots are -3 , ![\frac{2}{3}](https://tex.z-dn.net/?f=%5Cfrac%7B2%7D%7B3%7D)
We know that, for any quadratic equation of form
with roots
then,
Sum of roots
= ![\frac{-b}{a}](https://tex.z-dn.net/?f=%5Cfrac%7B-b%7D%7Ba%7D)
Product of roots (
= ![\frac{c}{a}](https://tex.z-dn.net/?f=%5Cfrac%7Bc%7D%7Ba%7D)
Now, for given quadratic equation
= -3 and
= ![\frac{2}{3}](https://tex.z-dn.net/?f=%5Cfrac%7B2%7D%7B3%7D)
hence Sum of roots = ![\frac{-7}{a}](https://tex.z-dn.net/?f=%5Cfrac%7B-7%7D%7Ba%7D)
![x_{1} + x_{2} = \frac{-7}{a}](https://tex.z-dn.net/?f=x_%7B1%7D%20%2B%20x_%7B2%7D%20%3D%20%5Cfrac%7B-7%7D%7Ba%7D)
![-3 + \frac{2}{3} = \frac{-7}{a}](https://tex.z-dn.net/?f=-3%20%2B%20%5Cfrac%7B2%7D%7B3%7D%20%3D%20%5Cfrac%7B-7%7D%7Ba%7D)
on solving we get "a" = 3
Now product of roots = ![x_{1} \times x_{2} = \frac{b}{3}](https://tex.z-dn.net/?f=x_%7B1%7D%20%5Ctimes%20x_%7B2%7D%20%3D%20%5Cfrac%7Bb%7D%7B3%7D)
![-3 \times \frac{2}{3} = \frac{b}{3}](https://tex.z-dn.net/?f=-3%20%5Ctimes%20%5Cfrac%7B2%7D%7B3%7D%20%3D%20%5Cfrac%7Bb%7D%7B3%7D)
b = -6
hence, the values of a and b are 3, -6.

The way to find percent is divide the whole by the nearest whole, and then multiply by 100.
Example:
35/38 * 100/100 = <em>percentage number(fraction or percent)</em>
Answer:
Here:
Step-by-step explanation:
You choose 2,4,6,8,10 as your solution points, or in other words the numbers you with substitute in for x.
The equation is:
y= 1/2x+1
So what we would do is take one number from the list above (2,4,6,8.10) and put it in for are.
So, Thats how you do it, I attached a completed version of your paper below!
