Axis of symmerty from form
ax²+bx+c is -b/2a
the axis of symetry is the x value of the vertex so just put the axis of symetry for x an evaluate

4x²-8x-3
-b/2a=-(-8)/(2*4)=8/8=1

input for x
4(1)²-8(1)-3=4-8-3=-7

(1,-7) is vertex

Answer

$\frac{ 6 {y}^{4} {w}^{2} }{{x}}$

Step-by-step Explanation

$\huge \frac{12 {x}^{3} {y}^{6} {w}^{5} }{ 2{x}^{4} {y}^{2} {w}^{3} } \\ \\ \huge= \frac{6 {x}^{3} {y}^{6} {w}^{5} }{{x}^{4} {y}^{2} {w}^{3} } \\ \\ \huge = 6 {x}^{3 - 4} {y}^{6 - 2} {w}^{5 - 3} \\ \\ \huge= 6 {x}^{ - 1} {y}^{4} {w}^{2} \\ \\ \huge = \frac{ 6 {y}^{4} {w}^{2} }{{x}^{1}} \\ \\ \huge = \frac{ 6 {y}^{4} {w}^{2} }{{x}}$
