Answer: LAST OPTION.
Step-by-step explanation:
In order to solve for the variable "x" from the expression , you need to follow these steps:
1) You need to multiply both sides of the equation by 3:
2) You need to multiply both sides of the equation by 6:
3) Finally, you can divide both sides of the equation by 15:
Given:
The leading coefficient of a polynomial is 8.
Polynomial roots are 1 and 2.
The graph passes through the point (4,5).
To find:
The 3rd root and the equation of the polynomial.
Solution:
The factor form of a polynomial is:
Where, a is a constant and are the roots of the polynomial.
Polynomial roots are 1 and 2. So, and
are the factors of the polynomial.
Let the third root of the polynomial by c, then is a factor of the polynomial.
The leading coefficient of a polynomial is 8. So, a=8 and the equation of the polynomial is:
The graph passes through the point (4,5). Putting , we get
Divide both sides by 48.
Therefore, the 3rd root on the polynomial is .
The slope-intercept form:
<em>add 27x to both sides</em>
<em>divide both sides by 9</em>
