Question

roots of equation x2-5x+6= 0 are​

Answer 1

Step-by-step explanation:

x^2 - 5x + 6 = 0

x^2 - (3+2)x + 6 = 0

x^2 - 3x - 2x + 6 = 0

x(x-3) - 2(x-3) = 0

(x-3)(x-2) = 0

if x-3 = 0 then x = 3

if x-2=0 then x = 2

so the roots of the equation are 3 and 2

Answer 2

Answer:

-2 & -3 are the roots of quadratic equation x2 + 5x + 6 = 0

Step-by-step explanation:

x2 + 3x + 2x +6=0

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

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

now,

x+3=0          x+2=0

x=-3              x=-2
