Compare the equation with general quadratic equation which is ax²+bx+c
Here a = 2
b = -5
c = -4
Sum of roots = -b/a = -(-5)/2 = 5/2
Product of roots = c/a = -4/2 = -2

Answer: Given:
》The given quadratic equation is 2x² - 5x - 4 = 0
To find:
Sum and product of roots.
Solution:
》2x² - 5x - 4 = 0
Here,
》a = 2, b = - 5 and c = - 4
Sum of roots = -b/a
Sum of roots = 5/2
Product of roots = c/a
Product of roots = -2
The sum and product of roots is 5/2 and -2 respectively.
