Question

$10x - \frac{1}{x} = 3$
factorisation

Answer 1

$\bf HELLO \: \: DEAR,$


$\bf 10x - 1/x = 3 \\ \\ \bf (10x^{2} - 1)/x = 3 \\ \\ \bf 10x^{2} - 1 = 3x \\ \\ \bf 10x^{2} - 3x - 1 = 0 \\ \\ \bf 10x^{2} - 5x + 2x - 1 = 0 \\ \\ \bf 5x(2x - 1) + 1(2x - 1) = 0 \\ \\ \bf (5x + 1)(2x - 1) = 0 \\ \\ \bf x = -1/5 , x = 1/2$
