Question

Find a and b so that 2-√5/2+ √5=a+b√5

Answer 1

Answer:

2 & 1/2

Step-by-step explanation:

2-√5/2+ √5=a+b√5

2+√5/2=a+b√5

a=2 and b=1/2

Answer 2

Step-by-step explanation:

2 - √5/2 + √5 = a + b√5

=> 2 - √5/2 + 2√5/2 = a + b√5

=> 2 + √5/2 = a + b√5

By comparison of both L.H.S. and R.H.S the values of a and b are 2 and 1/2 respectively.
