Answer:
Option 1: 1430p + 2200 = -4001
Step-by-step explanation:
Given that:
1.43p + 2.2 = -4.001
We can replace:
1.43p by 1430p * 10^-3
2.2 by 2200 * 10^-3
-4.001 by -4001* 10^-3
So the equation will become:
1430p * 10^-3 + 2200* 10^-3 = -4001 * 10^-3
Taking 10^-3 common from both side
(1430p + 2200)* 10^-3 = -4001 * 10^-3
Cancelling 10^-3 from both sides we get:
1430p + 2200 = -4001

<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:
7(a+2b)
Step-by-step explanation:
To factor an expression, you want to find the greatest common factor (GCF). I know that 7 can go into both 14 and 7, so my GCF would be 7. If I divide both 7a and 14b by 7, I get a and 2b. This means that my answer would be 7(a+2b) as that simplifies to 7a+14b. Hope that was helpful!
