Question

35. If 7-√5 / 7+√5= a +b√5, then find the value of a and b.​

Answer 1

Therefore a=27/22 and b=-5/22

Answer 2

• a = (27 - 7 √5)/(22) - b √5
• b = [(22a - 27 + 7√5) √5]/110

For finding

1. a = Solve for a by simplifying both sides of the equation, then isolating the variable.
2. b = Solve for b by isolating the variable by dividing each side by factors that don't contain the variable.
