Question

find the roots of the following equations2/5x square -x-3/5=0​

Answer 1

Answer:

x = $-\frac{1}{2}$ , 3

Step-by-step explanation:

As the given equation is a quadratic equation so we'll basically use the brute-force technique to find its solution:

$\frac{2}{5}x^{2}$ - 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

2x + 1 = 0,   x - 3 =0

x = -$\frac{1}{2}$,  x = 3
