1.	Find x^2+√2x-4;if x=√3 and x=-2√2
Answer» ANSWER: ${x}^{2} + \sqrt{2} x - 4 \\ x = \sqrt{3} \\ {( \sqrt{3} )}^{2} + \sqrt{2} \sqrt{3} - 4 \\ = 3 + \sqrt{6} - 4 \\ = \sqrt{6 } - 1$

Answer»

${x}^{2} + \sqrt{2} x - 4 \\ x = \sqrt{3} \\ {( \sqrt{3} )}^{2} + \sqrt{2} \sqrt{3} - 4 \\ = 3 + \sqrt{6} - 4 \\ = \sqrt{6 } - 1$
