Answer: 2

Step-by-step explanation: 2tan²45 + cos²30 - sin²60

                                           ⇒2×1² + (√3/2)² -  (√3/2)²

                                           ⇒ 2 + 3/4 - 3/4

                                           ⇒  \frac{8 + 3 - 3 }{4}

                                           ⇒   \frac{8}{4}

                                                   = 2
