Answer:
y = 2(x + 3)² - 4
Step-by-step explanation:
The equation of a parabola in vertex form is
y = a(x - h)² + k
where (h, k) are the coordinates of the vertex and a is a multiplier
Using the method of completing the square
y = 2x² + 12x + 14 ← factor out 2 from the first 2 terms
= 2(x² + 6x) + 14
To complete the square
add/subtract ( half the coefficient of the x- term)² to x² + 6x
y = 2(x² + 2(3)x + 9 - 9 ) + 14
= 2(x + 3)² - 18 + 14
= 2(x + 3)² - 4 ← in vertex form
Answer:
10 • (x - 2y + 3z)
? if thats the answer.
and y = 5/2 = 2.500 for the - 2y = -5 one. if they are both combined please comment under mine.
10 minutes left of homework
The equation was just flipped around, it will equal the same no matter what.
I hope this helps!! :)
