Answer:

Answer is h = 7/6

k = 23/12

Step-by-step explanation:

y = a(x - h)2 + k

where the vertex is (h, k).

y = 3(x2 - (7/3)x + (49/36)) + (23/12)

y = 3(x - (7/6))2 + (23/12)

h = 7/6

k = 23/12

Step-by-step explanation:

a=3 , b=-7 , c=-6

 {b}^{2}  - 4ac = ( { - 7)}^{2} - 4 \times 3 \times  - 6

 {b}^{2}  - 4ac = 49 + 72

 {b}^{2} - 4ac  = 121 \\

x =  \frac{  - b +  -  \sqrt{ {b}^{2}  - 4ac} }{2a}  \\

x =  \frac{ -7 +  -  \sqrt{121} }{2 \times 3}

x =  \frac{7 + 11}{6}  \:  \: or \: x =  \frac{7 - 11}{6}

x =  \frac{18}{6}  \: or \: x =  \:   \frac{ - 4}{6}

x = 3 \: or \: x =  \frac{ - 2}{3}
