Answer:
The answer is 8
Explanation:
f(x) = 5x² - x + 2
Using the remainder theorem
To find the reminder substitute the value of x into the above function and solve
That's
x + 1 = 0
x = - 1
So we have
f(-1) = 5(-1)² - ( - 1) + 2
f(-1) = 5 + 1 + 2
f(-1) = 6 + 2
We have the final answer as
8
Hope this helps you
