Answer:
The answer to your question is: The second option is correct
Step-by-step explanation:
Data
x³ + 4x² - 43x - 10 by x-5
Synthetic division
1 4 -43 - 10 5
5 45 10
1 9 2 0
Result x² + 9x + 2
1. A quadratic equation has the following form: ax²+bx+c.
2. The leading coefficient is the number that is attached to the variable with the highest exponent. Then, the "a" is the leading coefficient of the quadratic equation.
3. The problem says that the leading coefficient is 1 (a=1) and the roots of the quadratic equation are 5 and -3. Then, you have:
(x-5)(x+3)=0
4. When you apply the distributive property, you obtain:
x²+3x-5x-15=0
x²-2x-15=0
5. Therefore, the answer is:
x²-2x-15=0
(1/3)2= 2/3 cups butter
(1/3)24= 8 oz marshmallows
(1/3)14= 4 2/3 cups rice crispy
