(CO)

10 plus or minus the square root of 125 all divided by 5


Answer:



= (10 + √(125))/5

= [10 ± √(5*5²)]/5

= [10 ± 5√(5)]/5

= 10/5 ± [5√(5)]/5

= 10/5 ± (√5) * (5/5)

= 10/5 ± (√5) * (1)

= 10/5 ± (√5)

= 2 ± √5

Solution ∈ {-0.2360679774998, 4.2360679774998}

>>> final answer: 2 ± √5 or ∈ {-0.2360679774998, 4.2360679774998}
