Question

x^2-3✓5x+10=0 find the roots of the given equation

Answer 1

By using qudratic formula,

x=-b±squareroot of b2-4ac/2a

x=3root5±squareroot of (3 root 5)2 -4(1)(10)/2

x=3root5± squareroot of 45-40/2

x=3root5 ± squareroot of 5/2

x=3root5+root5/2 (or) 3root5-root5/2

x=4root5/2 (or) 2root5/2

x=2root5 (or) root5

hope u got it ...
