Question

Find the zeroes of the following quadratic polynomials and verify the relationship between the
zeroes and the coefficients.
i)5x^2+2x​

Answer 1

Solution:

» 5x² + 2x = 0

» x (5x + 2) = 0

» x = 0 or x = -2/5

Here a = 5, b = 2 and c = 0

Sum of zeroes = - 2/5

Also, -b/a = -2/5,

Product of zeroes = 0

Also, c/a = 0

Hence verified.
