Question

solve graphically and compare your answer with algebraic solution either by factorization or formula method. y = x² -5x +6...​

Answer 1

Answer:

solutions are x=2 and x= 3

Step-by-step explanation:

$y = {x}^{2} - 5x + 6 \\ = {x}^{2} - 3x - 2x + 6 \\ = x(x - 3) - 2(x - 3) \\ = (x - 2)(x - 3)$

so y=0 gives (x-2)(x-3)=0

so x=2 and x =3
