Answer:
The equation in standard form is:
Step-by-step explanation:
Since they give you the x-intercepts (the zeros of the quadratic expression) one knows that the binomials: (x-(-3)) and (x-4) must be factors of the quadratic expression.
We can therefore write the equation as:
using the binomial factors given above, and a numerical factor "k" that we can determine by using the information that the graph passes through the point (2,-20):
Then,the equation can be written as:
where we wrote the equation already in standard form
Answer:
x=-7
Step-by-step explanation:
add 4 to both sides. leaving you with x=-7
Hello again
The correct option is : D
Good luck!
Answer:
I believe the answer is the third option.
Step-by-step explanation:
hope this helps and is right :)
1) the answer to the radical is x^3+6x^2+12x+ 8
2) simplify this : x^3+6x^2+12x+ 8 + 3 = 27, into
3) this : x^3+6x^2+12x+ 11 = 27
4)Subtract 27 from both sides
x^3+6x^2+12x -16= 0
5) Use cubic formula.
x = 0.884499
