Question

Solve the quadratic equation
$x^{2} - \frac{3x}{10} - \frac{1}{10} = 0$
​

Answer 1

Step-by-step explanation:

Taking LCM

$10 {x}^{2} - 3x - 1 = 0$

by Middle term splitting

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

$2x - 1 = 0 \\ 2x = 1 \\ x = \frac{1}{2}$

$5x + 1 = 0 \\ x = - \frac{1}{5}$

Roots are

$x = \frac{1}{2} \: \: and \: \: - \frac{1}{5}$
