Find the zeroes of the polynomial \(t^3 - 2t^2 - 15t\) 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 \(=\)
Sum of product of zeroes taken two at a time \(=\)
Answer variants:
undefined
\(t = 5\)
\(t = 3\)
\(t = -5\)
\(t = 1\)
\(t = 0\)
\(t = -3\)
