Question

Help me plz thank you

Answer 1

x= -2

x=-2, y= 10


that ha sto be the total

Answer 2

`\text{Axis of symmetry: }x=-2\\\text{Vertex: }x=-2,\ y=10`

Explanation:

`y=-2x^2-8x+2\\\\\text{Solving }y=0:\\-2x^2-8x+2=0\\x=-2\pm√(5)\text{ (Using the quadratic formula)}\\\\\text{Finding mid-point (x-coordinate):}\\(-2+√(5)-2-√(5))/(2)=-2\\\\\therefore\text{Vertex: }x=-2,\ y=10\\\text{Axis of symmetry: }x=-2`
