Given f(x) = x^2 + kx -15, and the remainder when f(x) is divided by x-2 is -23, then what is the value of k?

k=-6

Step-by-step explanation:

f(2)=-23, 4+2k-15=-23. 2k=-12. K=-6

1.5%

step-by-step explanation:

for this case we must apply distributive property to the following expression:

the distributive property states that:

then, when applying the property we have to multiply the -2 for each term within the parenthesis:
