Answer:
Step-by-step explanation:
101/12
Answer:
0.35
Explanation:
<u>Follow the branch B and then branch D</u>
- multiply both the selected probabilities to calculate total probability.
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
The correct answer is C, if you use the distributive property and multiply all of them by each other you would get x^3+2x^2+3x+6.
Hope this helps :-)
