Answer:

I'mnot sure if you're asking for its roots..but here you go :)

Step-by-step explanation:

= 6 {x}^{2} + 19 + 9 {x}^{2}   - 8 \\  = (6 {x}^{2}  + 9 {x}^{2} ) + (19 - 8) \\  = 15 {x}^{2}  + 8 \\ 15 {x}^{2}  =  - 8 \\  {x}^{2}  =   - \frac{8}{15} \\  \sqrt{ {x}^{2} }  =  \sqrt{  - \frac{8}{15} }   \\ x =  \sqrt{ \frac{8}{15}}  \times  \sqrt{ - 1}  \\ x =  \sqrt{ \frac{8}{15} }  \times i \\  x1 = 0.7302i \\ x2 =  - 0.7302i

Y =ax² + bx +c

1) Point (0,7)

7 = a*0² +b*0 +c
c = 7
y=ax² + bx + 7

2) Point (1,4)
4=a*1² + b*1 + 7, ----> 4 = a +b + 7, ------> a+b= - 3
3) Point (2, 5)
5=a*2² + b*2 + 7, ----> 5=4a+2b +7,---> -2=4a+2b, ----> -1=2a + b

4)  a+b= - 3, ----> b= -3 - a (substitute in the second equation)
    2a+b= -1
2a - 3 - a = -1, ----> a - 3 = -1, a =2

5) a+b= - 3
    2 + b = -3
b = -5

y=2x² - 5x + 7
