Question

For what values of a the following express
ion is +ve?
i) x2 - 5x+6 and give detailed explanation.
​

Answer 1

Answer:

3 and 2

Step-by-step explanation:

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

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

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

x-3 = 0 and x-2 =0 and x = 3,x =2

this implies x = 3,2

Answer 2

ANSWER

$⟹ {x}^{2} - 5x + 6 \\ \\ ⟹ {x}^{2} - 2x - 3x + 6 \\ \\ ⟹x(x - 2) - 3(x - 2) \\ \\ ⟹(x - 2)(x - 3) \\ the \: value \: of \: x \\ ⟹x - 2 = 0 \\ ⟹x = 2 \\ ⟹x - 3 = 0 \\ ⟹x = 3$
