Question

Y=3x^2+12x-27 in vertex

Answer 1

Answer:(3,−2)

Step-by-step explanation:

Answer 2

Answer:

Complete the square to convert to vertex form.

Step-by-step explanation:

y =  

3

x

2

+ 12x - 15

y = 3(

x

2

+ 4x + n - n) - 15

n =  

(

b

2

)

2

n = 4

y = 3(

x

2

+ 4x + 4 - 4) - 15

y = 3(

x

2

+ 4x + 4) - 12 - 15

y = 3(

x

2

+ 4x + 4) - 27

y = 3

(

x

+

2

)

2

- 27

In the form y = a

(

x

−

p

)

2

+ q, the vertex can be found at (p, q). So, the vertex is (-2, -27).

Hopefully my explanation helps!
