Question

Find the zeroes of the following quadratic polynomials and verify the relationship between
the zeroes and the coefficients.
X square – 2x – 8​

Answer 1

Sol:

x² - 2x - 8 = 0

x² - 4x + 2x - 8 = 0

x(x - 4) + 2( x- 4) = 0

( x - 4) or (x + 2) =0

x - 4 = 0 or x + 2 =0

x = 4 or x = -2

The zero of Quadratic polynomial is 4 or -2.
