Question

plz solve 1 question

Answer 1

For these question answer is a = 1 and b = 0

Answer 2

$let = \: \alpha \: a - b \\ \beta \: \: a \\ \gamma \: a + b \\ a - b + a + a + b = 3 \\ 3a = 3 \\ a = 1 \\ a + b \times a \times a - b = - 1 \\ put \: a = 1 \\ 1 - b \times 1 \times 1 + b \\ 1 - b {?}^{2} = - 1 \\ b = \sqrt{2}$
