Answer 2

Answer:

Heyy mate...Good afternoon...here's you're answer...

Step-by-step explanation:

Given:

$x \geqslan - 1 \div \: x = - 1$

To Find:

$x \geqslan}^2} + 1 \div x}^{2} = \frac{ \frac{?}{?} }{?}$

$olution:

W.K.T

$(a - b) {}^{2} \di = a {}^{2} + b {}^{2} - 2ab$

So...by squaring the equation on both sides...we get...

$(x \geqslan - 1 \div \: x) {}^{2} = ( - 1) {}^{2} \\ x {}^{2} + (1 \div x) {}^{2} - 2 \times x \times 1 \div x = 1 \\ x {}^{2} + (1 \div x) {}^{2} = 1 + 2 \\ x {}^{2} + 1 \div x {}^{2} = 3$
