1. What is the remainder when x^2+4 is divided by x-2?2. Evaluate f(-1) using substitution: f(x)=2x^3-3x^2-18x-83. The point (1,0) lies on the graph of p(x)=x^4-2x^3-x+2True or false4. If x-1 is a factor of p(x)=x^3-7x^2+15x-9, which of the following represents the complete factorization for p(x)?A. (x-3)(x+4)(x+1)B. (x-3)(x-3)(x-1)C. (x-3)(x+3)(x-1)D. (x-3)(x+3)(x+1)
Question
Answer:
1.The remainder is 8. (x2 + 4)/(x - 2) = (x + 2) + 8/(x - 2) or x2 + 4 = (x - 2)(x +Β + 82. 5
3.not sure but maybe true
4.divide P(x) by (x-1) to get the quadratic equation... from which can be solve using any method in finding the roots of quadratic equation....
