Question

(x/5+5/7)(x/5+3/5)
Solve this by using 4th identity........
​

Answer 1

Answer: $\frac{x^2}{25} + \frac{3x}{35} + \frac{3}{7}$

Step-by-step explanation:

$( \frac{x}{5} + \frac{5}{7} )+(\frac{x}{5} + \frac{3}{5} )$

=> $(\frac{x}{5}) ^2+ (\frac{5}{7}+\frac{3}{5})\frac{x}{5} + (\frac{5}{7}*\frac{3}{5})$      [Formula:- (x + a)(x + b) = x² + (a + b)x + ab]

=> $\frac{x^2}{25} + \frac{3x}{35} + \frac{3}{7}$
