Question

find the roots of 2/5x²-x-3/5=0 by Factorisation method​

Answer 1

Answer:

-1/2 and 3

Step-by-step explanation:

Answer 2

Step-by-step explanation:

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

$\frac{2}{5}x(x - 3) - \frac{1}{5}(x - 3) = 0 = >$

$(x - 3)( \frac{2}{5}x - \frac{1}{5}) = 0 = >$

$(x - 3) = 0 \: or \: ( \frac{2}{5}x - \frac{1}{5} ) = 0 = >$

x=>3 and x=> 1/2. Hope it helps you.
