Is {-2, 1} a solution set to x squared take away 2x takeaway three equals x take away one

No! {-2, 1} is not a solution set to the given equation.

Step-by-step explanation:

The statement  X squared take away 2X Takeaway three equals X take away one can be written in mathematical terms as follows:

X² - 2X - 3 = X - 1

⇒ X² - 2X - 3 - X + 1 =0

⇒ X² - 3X - 2 = 0

Now, substitute x= -2 and see if the equation is satisfied.

⇒ (-2)² -3(-2) - 2 = 4 + 6 - 2

= 8 ≠ 0

So, -2 is not a solution to the equation.

Now, check for x = 1.

⇒ (1)² - 3(1) - 2 = 1 - 3 - 2

= -4 ≠ 0

⇒ x = 1 is not a solution as well.
