Question

can anyone confirm the answer of this please​

Answer 1

Step-by-step explanation:

➪$\frac{(4 + \sqrt{5)} \times (3 - \sqrt{5)} }{4} = a - b \sqrt{5}$

➪$\frac{12 - 4 \sqrt{5 } + 3 \sqrt{5} - 5 }{4} = a - b \sqrt{5}$

➪$\frac{7 - \sqrt{5} }{4} = a - b \sqrt{5}$

➪$- a = - b \sqrt{5} - \frac{7 - \sqrt{5} }{4}$

➪$a = b \sqrt{5 } + \frac{7 - \sqrt{5} }{4}$

☞︎︎︎$a = b \sqrt{5} + \frac{7 - \sqrt{5} }{4}$
