Answer:
Step-by-step explanation:
At first you need to turn roots into factors and then multiply the
then you have
f(x) = a(x + 2)(x -5)^2
f(x) = a(x + 2)(x^2 - 10x + 25)
f(x) = a(x^3 - 8x^2 + 5x + 50)
You can use either synthetical or the factor
theorem
f(-2) = a(-8 - 8(4) + 5(-2) + 50) = a(0) = 0.. check, f
=-2
€(5) = a(125 - 8(25) + 5(5) + 50) = a(0) = 0 check, f
= 5 works
Then divide it to the the second multi
And you should get x^2 - 3x - 10 = (x - 5)(x + 2),
where the other two zeros are X =5 , and x=-2

Step-by-step explanation:
(5x + 2)/x² = 5/x + 2/x²
= 5x^-1 + 2x^-2
Which is not a polynomial
The slope is the number besides x which in this case is 14 while your t intercept is 9
It would be A as your answer
y=x^2 - 10x +2
Use the form ax^2 + bx + c to find the values of a, b,and c.
a = 1 ( no number in front of the x^2)
b = 10
c = 2
Vertex form is a(x+d)^2 + e
Solve for d using d= b/2a
d = 10 / 2
d = 5
Find e using e = c - b^2/4a
e = 2 - 10^2/4
e = 2 - 25
e = -23
Vertex = d,e
Vertex = (5, -23)
