1/(x-2)+1/(x+3)=1/5 solve the problem for me

Gennadij [26K]

<h3>Final value : x² -9x - 11</h3>

════════════════════

$\frac{1}{(x - 2)} + \frac{1}{(x + 3)} = \frac{1}{5}$

$\frac{(x + 3) + (x - 2)}{(x - 2)(x + 3)} = \frac{1}{5}$

$\frac{2x + 1}{ {x}^{2} + 3x - 2x - 6 } = \frac{1}{5}$

$\frac{2x + 1}{ {x}^{2} + x - 6} = \frac{1}{5}$

2x + 1 = ⅕ × (x² + x - 6)

2x + 1 = ⅕x² + ⅕x - 6/5

1/5x² +1/5x - 2x - 6/5 - 1 = 0

1/5x² -9/5x - 11/5 = 0

x² - 9x - 11 = 0. #times by 5

Which expression is equivalent to Assume x > 0 and y 0.

Svetach [21]

we have

$\sqrt{\frac{55x^{7}y^{6}}{11x^{11}y^{8}}}$

we know that

$\sqrt{\frac{55x^{7}y^{6}}{11x^{11}y^{8}}} =\sqrt{\frac{55}{11}\frac{x^{7}}{x^{11}}\frac{y^{6}}{y^{8}}} \\ \\= \sqrt{\frac{5}{x^{4} y^{2}}} \\ \\ =\frac{\sqrt{5}}{x^{2} y}$

therefore

<u>the answer is</u>

The expression equivalent is $\frac{\sqrt{5}}{x^{2} y}$
