At park junior high, 10%, or 160, of the students, play a musical instrument. how many students attend the school?

Answers

none of the above.

for one of the equations to be used in the process, there has to be a 2x^2 term in the equation since 2x squared is 2x^2.

since there is only a x^2 term in the first equation, we cannot derive a 2x+4 from completing the square.

solving with completing the square

x^2=-4x+3

x^2+4x=3

x^2+4x+4=7

(x+2)^2=7

x+2=+-\sqrt{7}

x=2+-\sqrt{7}
