Question

what is the value of x^2 - 3x + 2 when x= -2

Answer 1

Answer:

12

Step-by-step explanation:

Substitute the value x=-2 in the equation x^2-3x+2 we get

x^2-3x+2=(-2)^2-3(-2)+2

=4+6+2

=12

Answer 2

Answer:

The value for the given equation is 12.

Step-by-step explanation:

As we have been given in the above question, there is a quadratic polynomial whose value is to be found at x = -2. Now we will put the given x value in the equation above and calculate the respective answer as below:

P (x) = $x^{2} -3x + 2$

And we have to put, x = (-2)

∴ P(-2) = $(-2)^{2} -3(-2) + 2$

= 4 + 6 + 2

= 12

Therefore the calculated value of the above-given polynomial is 12.

Hence the answer is 12.
