Question

Bo factored x^2 – 10xy + 16y^2 as follows

Answer 1

Line 1 x^2 – 10xy + 16y^2

Line 2 x^2 – 8xy – 2xy + 16y^2

Line 3 x(x – 8) – 2y(x – 8y)

Line 4 prime

A. Did Bo correctly factor the polynomial? Justify your response by explaining why it is is factored correctly or by showing the correct solution if it is not factored correctly.

B. Explain how you would know if a polynomial of the form ax^2 + bxy + cy^2 was prime?
