Elementary Algebra by Hall and Knight

Try with Hints

First hint

here ratio = 4:3

\(\Rightarrow boys =4x, girls=3x\)

given \((4x-8)=(3x-14)^{2}\)

Second Hint

\(\Rightarrow 4x-8=9x^{2}-84x+196\)

\(\Rightarrow 9x^{2}+196-84x=4x-8\)

\(\Rightarrow 9x^{2}-88x+204=0\)

Final Step


\(\Rightarrow x=6 or \frac{34}{9}\)

\(\Rightarrow 7x=42\) or non-integer

\(\Rightarrow 42 members.\)
