Question

!!!! ANSWER ASAP 40 POINTS !!!! the expression x^2-x-6 can be written as (x+2)(x+Z) where Z represents a number. What is the value of Z? (please explain the steps as well thank you very much)

Answer 1

Answer: -3

Explanation:

for an equation
`ax^2+bx+c` to factor you need to figure out what numbers add to b and multiply to c. In this case b is -1 and c is -6. It is easier because one of the numbers has already been figured out for you so what number combined with 2 will add to -1 and multiply to -6? the answer would be -3 because 2+(-3) is -1 and 2*(-3) is -6.
