Bro can somebody plz just help me answer this question!

Place the following steps in order to complete the square and solve the quadratic equation,

Since opening night, attendance at play a has increased steadily, while attendance at play b first rose and then fell. equations modeling the daily attendance y at each play are shown below, where x is the number of days since opening night. on what day(s) was the attendance the same at both plays? what was the attendance? play a: y = 8x + 191 play b: y = -x^2 + 26x + 126

I’m stuck on this equation, anyone got the answer?
