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
Answer:plz answer my question i need help
Step-by-step explanation:
Answer:
x = 6
Step-by-step explanation:
<u>Calculations:</u>
2(x + 4) = 20 (Distribute)
2x + 8 = 20 (Subtract 8 from both sides)
2x = 12 (Divide by 2 from both sides)
x = 6
<u>Verify:</u>
2(10) = 20 (Correct)
