<h3>Given</h3>
- Equation ax² + bx + c = 0
- One of the roots is twice the other
<h3>To find</h3>
<h3>Solution</h3>
Let the roots be p and q
<u>The sum and product of the roots:</u>
<u>The sum of the roots, considering p = 2q,</u>
And
<u>The product of the roots, considering p = 2q:</u>
And
<u>Substitute q with -b/(3a)</u>
- 2(-b/(3a))² = c/a
- 2b²/(9a²) = c/a
- 2b² = 9a²(c/a)
- 2b² = 9ac

<h3>Given</h3>
Quadratic equation
- ax² = bx + c = 0, with equal roots
<h3>To find</h3>
<h3>Solution</h3>
<u>Equal roots means the discriminant is zero:</u>
- D = √b² - 4ac
- √b² - 4ac = 0
- b² - 4ac = 0
- b² = 4ac
Answer:
x > - 
Step-by-step explanation:
Given
10 - 2(3x + 4) < 11 ← distribute and simplify left side
10 - 6x - 8 < 11
2 - 6x < 11 ( subtract 2 from both sides )
- 6x < 9
Divide both sides by - 6, reversing the symbol as a result of dividing by a negative quantity.
x >
⇒ x > - 
The boxplot provides the following information:
Minimum = 0
First quartile = 2
Median = 4
Third quartile = 7
Maximum = 9
The sum is 2+4+7+9 = 22
The unaccounted for participants is 24 - 22 = 2 (outliers).
Those who participated for 2 years or less is 2.
