Remainder theorem and factor theorem: If f(x) + x^6 – 5x^4 – 10x^2 + k...
I was given 2 problems to solve for home work, but don't quite know how to solve them. The teacher gave easy problems in school and left these two for home work. Please give me a hand as it is due for today..
1. If f (x) + x6 – 5x4 – 10x2 + k, find the value of k for which x - 1 is a factor of f (x). When k has this value, find another factor of f (x), of the form x + a, when a is a constant.
2. Find the value of a and b if f (x) = ax3 + bx2 +12 is exactly divisible by both (x + 1) and (x - 2). With these values a and b. solve the equation f (x) = 0
I need to show full working... Please help me..
