Solve the following quadratic equation by factorization : (5+x)/(5-x) – (5-x)/(5+x) = 3(3/4): x ≠ 5, -5
Solve the Following Quadratic Equation by Factorization Question: \[ \frac{5+x}{5-x}-\frac{5-x}{5+x}=\frac{15}{4}, \qquad x\ne 5,-5 \] Solution Given: \[ \frac{5+x}{5-x}-\frac{5-x}{5+x}=\frac{15}{4} \] Taking LCM on the left side: \[ \frac{(5+x)^2-(5-x)^2}{(5-x)(5+x)} =\frac{15}{4} \] Using the identity \(a^2-b^2=(a-b)(a+b)\): \[ \frac{\big[(5+x)-(5-x)\big]\big[(5+x)+(5-x)\big]} {25-x^2} =\frac{15}{4} \] \[ \frac{(2x)(10)}{25-x^2} =\frac{15}{4} \] \[ \frac{20x}{25-x^2} =\frac{15}{4} \] Cross-multiplying: \[ 80x=15(25-x^2) \] \[ 80x=375-15x^2 \] \[ 15x^2+80x-375=0 […]
