Answer:
below
Step-by-step explanation:
[tex]x.4 ( x-4) = 36 \\[/tex]
[tex]4x(x-4) = 36 \\[/tex]
[tex]4x^{2} - 16x = 36[/tex]
add -36 to both sides
[tex]4x^{2} - 16x - 36 = 36 -36 \\4x^{2} -16x - 36 = 0[/tex]
divide both sides by 2
[tex]\frac{4x^{2} - 16x - 36 }{4} = 0/4[/tex]
[tex]x^{2} -4x-9 = 0[/tex]
This is a quadratic equation
let's solve it by graphing it
The solution are the x-coordinates of the intersection points
The x-coordinates of the intersection points are approximatively -1.6 and 5.6
