Question

the roots of the quadratic equations X2 +5×+6=0 are
​

Answer 1

Answer:

x= -3 and -2

Step-by-step explanation:

x2+5x+6= 0

x2+2x+3x= 0

or, x(x+2)+3(x+2)= 0

or, x+2=0 and x+3=0

therefore, x=-2 and -3

Answer 2

Answer:

x2-5x+6=0

⇒(x−2)(x−3)=0

⇒x=2 and x=3

Therefore, x=2 and x=3 are roots of the given equation.
