Question

Find the sum of roots and product of roots for 2x2-5x-4=0.

Answer 1

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

• $\therefore$ Sum of roots = 5/2

• Product of roots = c/a

• $\therefore$ Product of roots = -2

$\therefore$ The sum and product of roots is 5/2 and -2 respectively.
