<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
Yes, you are right. To solve for a variable means to put it on one side by itself, in terms of the other variables or values. To move something to the opposite side you do the opposite operation. Then you do the same thing to both sides of the equation.

6.25 squared is 39.0625
Y + 2 < 5x.....y < 5x - 2....slope = 5...y int = -2.....less then means shading below the line....dashed line because no equal sign.
y + 3x > 4....y > -3x + 4....slope = -3....y int = 4....greater then means shaded above the line....dashed line because no equal sign
y > = 2x....slope = 2....goes thru the origin (0,0)....greater then means shading above the line....solid line because of the equal sign
