The zeros of a quadratic function are -8 and 5. Write the quadratic function in Standard Form.
1 answer:
Answer:
y = x² + 3x - 40
Step-by-step explanation:
Given the zeros are x = - 8 and x = 5, then the factors are
(x + 8) and (x - 5) and
y = (x + 8)(x - 5) ← expand factors
y = x² - 5x + 8x - 40, hence
y = x² + 3x - 40 ← in standard form

Answer:
Let's complete the square first.
y = x² + 6x + 3
= (x² + 6x + 9) - 6
= (x + 3)² - 6
Therefore, the vertex is (-3, -6) and since the coefficient of (x + 3)² is positive, the vertex is a minimum.

Answer:
x = 3
< D = 26
< E = 54
Step-by-step explanation:
I did the math
If 4y-2=26 then 4y=26+2
4y=28 divide both side by 4
y=28/4=7 opt A
