Find the zeroes of the polynomial

$4x^2 - 3x - 1$ by factorisation method and verify the relation between the coefficients and the zeroes of the polynomial.

Answer:

The zeroes are

and

Sum of the zeroes

$=$

Product of the zeroes

$=$

Answer variants:

$\frac{constant}{coefficient of x^{2}} = \frac{1}{4}$

$\frac{constant}{coefficient of x^{2}} = \frac{- 1}{4}$

$x = -\frac{3}{2}$

$x = 1$

$\frac{- coefficient of x}{coefficient of x^{2}} = \frac{- 3}{4}$

$x = \frac{4}{3}$

$x = \frac{-1}{4}$

$\frac{- coefficient of x}{coefficient of x^{2}} = \frac{3}{4}$
