If one root of 5x² + 13x + k = 0 be the reciprocal of the other root then the value of k is

Let the roots of equation be than other root will be

Product of two roots =

Product of the roots =

For the given equation 5x² + 13x + k = 0

a = 5 b = 13 c = k comparing with ax² + bx + c = 0

Product of the roots

k = 5

The ratio of the sum and product of the roots of the equation

7x² - 12x + 18 = 0 is

If one root of the equation 3x² - 10x + 3 = 0 is 1/3 then the other root is

If the sum of the roots of the equation kx² + 2x + 3k = 0 is equal to their product then the value of k is

The roots of a quadratic equation are 5 and - 2. Then, the equation is
