Move all terms to the left side and set equal to zero. Then set each factor equal to zero.
x= 3, 2

\boxed{\bold{x = 2, 3}}

Stepwise Solving:


\rightarrow \sf x^2-5x + 6 = 0


\sf use \ the \ formula : x = ( -b \pm √(b^2 - 4ac))/(2a) \ \ when \ ax^2 + bx + c = 0

Identify the coefficients:

  • a = 1
  • b = -5
  • c = 6

Solve for x:


\dashrightarrow \ \sf x=(-\left(-5\right)\pm √(\left(-5\right)^2-4 \ x \ 1 \ x \ 6))/(2 \ x \ 1)


\dashrightarrow \ \sf x=(\left5\right\pm √(\left25-24))/(2)


\dashrightarrow \ \sf x=(\left5\right\pm √(1))/(2)


\dashrightarrow \ \sf x=(\left5\right\pm1)/(2)


\dashrightarrow \ \sf x=(\left5\right+ 1)/(2) \ , (\left5\right- 1)/(2)


\dashrightarrow \ \sf x=(6)/(2) \ , \ (4)/(2)


\dashrightarrow \ \sf x= 3, \ 2
