Answer:

The coefficient of squared term is 1/9

Step-by-step explanation:

The vertex of parabola is (2.-3)

We know the vertex form of a standard parabola

y=a(x-h)^2+k,\text{ where (h,k) is vertex}

Plugging values of h and k, h= 2, k = -3

y=a(x-2)^2-3

Now, x=5, y=-2

-2=a(5-2)^2-3

-2=9a-3

9a=1

a=\frac{1}{9}

Thus, the coefficient of squared term is 1/9

2x² + 4x + 4 + x² + 1 = 180
Tasya [4]

Step-by-step explanation:

2 {x}^{2}  + 4x + 4 +  {x}^{2}  + 1 = 180

3 {x}^{2}  + 4x + 5 = 180

{3x}^{2}  + 25x - 21x - 175 = 0

x \times (3x + 25) - 7(3x + 25) = 0

(3x + 25) \times (x - 7) = 0

3x + 25 = 0 = x - 7 = 0

x =  -  \frac{25}{3}  = x = 7

= x_{1} =  -  \frac{25}{3} . \:  \:  x_{2} = 7
