Question

find the roots of equation by factorisation method 2/5x^2-x-3/5=0​

Answer 1

$\frac{2}{5} {x}^{2} - x - \frac{3}{5} = 0 \\ \\ 2 {x}^{2} - 5x - 3 = 0 \\ \\ 2 {x}^{2} - 6x + x - 3 = 0 \\ \\ 2x(x - 3) + 1(x - 3) = 0 \\ \\ (2x + 1)(x - 3) = 0 \\ \\ x = 3 \\ \\ x = - \frac{1}{2}$

hope it helps.
