A parabola has x-intercepts of (2, 0) and (-4, 0) and has a leading coefficient of 1. What is the equation of the parabola in standard form? *
9514 1404 393
Answer:
y = x^2 +2x -8
Step-by-step explanation:
For x-intercepts p and q, factors of the parabola's equation are (x-p) and (x-q). Since the leading coefficient is 1, those are the only factors.
y = (x -2)(x -(-4))
y = (x -2)(x +4) = x(x +4) -2(x +4) . . . . use the distributive property
y = x^2 +4x -2x -8 . . . . use the distributive property again
y = x^2 +2x -8 . . . . . . . .equation in standard form
Can somebody help please?

Solve the equations below by SHOWING YOUR WORK. This includes how you will isolate the variable and keep the equation balanced to get your answer. You must show your work and present your answer for credit. Just an answer will result in no credit. If you are not sure what this means, take a quick look at the videos or recorded lesson. A. B. X - 3.5 = 9.1
Answer:
[tex]X = 12.6[/tex]
Step-by-step explanation:
Given
[tex]X - 3.5 = 9.1[/tex]
Required
Solve for X
Add 3.5 to both sides
[tex]X - 3.5 +3.5 = 9.1 + 3.5[/tex]
[tex]X = 9.1 + 3.5[/tex]
[tex]X = 12.6[/tex]
