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
17.46% of 126 is 22
Divide 22 by 126:
Change the decimal into a percentage by multiplying the decimal by 100:
There are 4 9's in a deck.
The probability would be 4 / 52 = 0.07692
Rounded to the nearest hundredth = 0.08
