Question

sum of the roots of 2 X square + 3 X + 5 = 0​

Answer 1

$\huge\underline\mathrm{Solution}:-$

= 2x² + 3x + 5 = 0

= 2x² -5x +2x + 5 = 0

= x(2x - 5)+1 (2x - 5) = 0

= (2x = 5)(x + 1)

= x = 5/2 and x = -1

So, the roots of the given equation are 5/2 and -1.

Sum of the roots = -b / a

= 3/2
