Provide an appropriate response.If the polynomial 4x4 + 7x2 - 2 is to be factored completely, is the following answer correct? Explain.4x4 + 7x2 - 2 = (4x2 - 1)(x2 + 2)
What will be an ideal response?
No. The factor (4x2 - 1) can be factored further as (2x + 1)(2x - 1). Thus, the polynomial is factored completely as (2x + 1)(2x - 1)(x2 + 2).
