Answer:
x -22
Step-by-step explanation:
Sum = -7 (-22+15 = -7)
Product = -330 (-22*15 = -330)
Factors = -22 , 15
x² - 7x - 330 = x² +15x - 22x - 22 *15
= x(x + 15) -22(x + 15)
= (x +15)(x -22)
![\frac{x^{2}-7x-330}{x + 15}=\frac{(x+15)(x-22)}{(x+15)}\\\\ =x - 22](https://tex.z-dn.net/?f=%5Cfrac%7Bx%5E%7B2%7D-7x-330%7D%7Bx%20%2B%2015%7D%3D%5Cfrac%7B%28x%2B15%29%28x-22%29%7D%7B%28x%2B15%29%7D%5C%5C%5C%5C%20%3Dx%20-%2022)
C is the answer because 2/3y=6
Y=6*3/2
Y=9
A polynomial in standard form only means that you put it in order of descending x values. Multiplying out those 2 factors gives us
. Combining like terms and we have
. That's in standard form.
( b ) is the answer I think :)
