Find the zeroes of the polynomial \(3x^2 + 4x - 4\) 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{- coefficient of x}{coefficient of x^{2}} = \frac{4}{3}

\(x = \frac{2}{3}\)

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

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

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

\(x = -2\)

\(x = \frac{-1}{4}\)

\(x = -\frac{3}{2}\)
