Question

solve and check
x^2-3x+2=0

Answer 1

So to set this up, you need to find all values of x such that the function = 0.

Answer 2

To do this you can split up the polynomial into a multiplication:

\[x^2 -3x + 2 = 0 --> (x-2)(x-1) = 0\]

Answer 3

So, because when x = 2 and x = 1 the function is = 0, you can say that x = 2 and x = 1 and that is the answer.

Answer 4

Keep in mind, you have to know how to split up polynomials in order to be able to solve questions like these.
