Answer:
x=2
x=3
Explanation:
This seems like factorisation
X^2-5x+6
To factorise, you will look for two numbers that when multiplied together it will give 6 and when added it will give -5
Back to the question, the two numbers that can be used to multiple 6 and when added it will gives -5 is -3×-2
x^2-3x-2x+6
x(x-3)-2(x-3)
(x-3)(x-2)
Which can be solved further,
(x-3)=0
Add 3 to both sides
x=3
(x-2)=0
Add 2 to both sides
x=2
