A
The difference is a binomial with a degree of 5.B
The difference is a binomial with a degree of 6.C
The difference is a trinomial with a degree of 5.D
The difference is a trinomial with a degree of 6.24
One factor of is (x – 2). What are all the roots of the function? Use the Remainder Theorem.
A
x = 1, x = 2, or x = 4B
x = –2, x = 1, or x = 2C
x = 2, x = 4, or x = 16D
x = –16, x = 2, or x = 1625
What is the difference of the polynomials?(–2x3y2 + 4x2y3 – 3xy4) – (6x4y – 5x2y3 – y5)
A
–6x4y – 2x3y2 + 9x2y3 – 3xy4 + y5B
–6x4y – 2x3y2 – x2y3 – 3xy4 – y5C
–6x4y + 3x3y2 + 4x2y3 – 3xy4 + y5D
–6x4y – 7x3y2 + 4x2y3 – 3xy4 – y5Did you find these answers helpful?
