Question

if a square + b square is equal to 13 and ab is equal to minus 12 find a minus b and a square minus b square​

Answer 1

Answer:

$a {}^{2} + b {}^{2} = 13 \\ ab = - 12 \\ (a - b) {}^{2} = a {}^{2} + b {}^{2} - 2ab \\ (a - b) {}^{2} = 13 - 2 \times ( - 12) \\ (a - b) {}^{2} = 13 + 24 = 37 \\ a - b \: = \sqrt{37}$
