Answer: OPTION C
Step-by-step explanation:
Given the quadratic equation [tex]x^2 - 7x + 10[/tex] and the value of the variable "x" [tex]x = -2[/tex], you need to substitute the given value of the variable. Then:
[tex]=(-2)^2 - 7(-2) + 10[/tex]
And finally, you need to evaluate.
Remember the multiplication of signs:
[tex](+)(+)=+\\(-)(-)=+\\(-)(+)=-[/tex]
Therefore, you get the following result:
[tex]=4+14 + 10[/tex]
[tex]=28[/tex]
This matches with the option C.
