Question

if alfa and bita are the zeroes pf polynomial x square -px+q find the value of alpha square + bita square

Answer 1

hey, mate here is ur solution
$we \: know \: that \: \\ \alpha + \beta = (p \div 1) \\ and \: \alpha \beta =( q \div 1) \\ \alpha {}^{2} + \beta {}^{2} = (\alpha + \beta ) {}^{2} - 2 \alpha \beta \\ \alpha {}^{2} + \beta {}^{2} =( p) {}^{2} - 2q$
