Answer:
- 4√5 or 3√5
Step-by-step explanation:
⇒ x^2 + √5 x - 60 = 0
Using Splitting middle term
which says split the middle( with x ) in two parts such that their product is the product of constant term and term with x^2.
Here, we found a satisfying pair is 4√5 - 3√5
⇒ x^2 + √5 x - 60 = 0
⇒ x^2 +( 4√5 - 3√5 )x - 60 = 0
⇒ x^2 + 4√5 x - 3√5 x - 60 = 0
⇒ x( x + 4√5 ) - 3√5( x + 4√5 ) = 0
⇒ ( x + 4√5 )( x - 3√5 ) = 0
⇒ x = - 4√5 or x = 3√5
