Question

factorise the equation x²-3x-1 and thus find it's roots​

Answer 1

You will have to use the quadratic formula and get factors and

find its 2 roots

Quadratic formula: b±√(b^2-4ac))/2a

here,

a= 1

b= -3

c= -1

After substituting the final roots would be

• x= (-3+√13)/2
• x= (-3-√13)/2

HOPE THIS WILL HELP YOU!
