Answer:
x = -8
Step-by-step explanation:
16+6-6x-4=-7x+3+7
Combine like terms
18 -6x = -7x+10
Add 7x to each side
18-6x+7x = -7x+7x+10
18+x = 10
Subtract 18 from each side
18+x-18 = 10-18
x = -8
we can see that
the given curve is parabola
so, firstly we will find vertex
vertex is (4,0)
we can write equation of parabola

now, we can plug values
and we get

we can also write it as
