Find a quadratic polynomial, the sum and product of whose zeroes are \(\frac{21}{8}\) and \(\frac{5}{16}\), respectively. Also, find its zeroes of the polynomial by factorisation.
Answer:
Quadratic polynomial \(=\)
The zeroes are and .
Answer variants:
\(x^2 - \frac{21}{8}x + \frac{5}{16}\)
\(x = -\frac{1}{8}\)
\(x^2 + \frac{21}{8}x + \frac{5}{16}\)
\(x = \frac{1}{8}\)
\(x = -\frac{5}{2}\)
\(x = \frac{5}{2}\)
