Question

(−2 − √3)(−2 + √3) simplified​

Answer 1

Answer:

1

Step-by-step explanation:

(- 2 - $\sqrt{3}$ )(- 2 + $\sqrt{3}$ )

each term in the second factor is multiplied by each term in the first factor.

- 2(- 2 + $\sqrt{3}$ ) - $\sqrt{3}$ (- 2 + $\sqrt{3}$ ) ← distribute both parenthesis

= 4 - 2$\sqrt{3}$ + 2$\sqrt{3}$ - 3 ← collect like terms

= 1
