Question

(x-2+√3)(x+2+√3) pls help me solve

Answer 1

Answer:

$x^{2} +2\sqrt{3} x-1$

Step-by-step explanation:

(x-2+√3)(x+2+√3)                                        

Let (x-2) be A, $\sqrt{3}$ be B

and now we proceed as follows

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