2015年5月10日 · How do you factor x4 + x2 + 1? x4 +x2 + 1 = (x2 + x + 1)(x2 −x + 1) To find this, first notice that x4 +x2 + 1> 0 for all (real) values of x. So there are no linear factors, only …

Check that the middle term is two times the product of the numbers being squared in the first term and third term. 4x = 2⋅(2x)⋅1 4 x = 2 ⋅ (2 x) ⋅ 1. Rewrite the polynomial. (2x)2 − 2⋅(2x)⋅1+12 (2 …

把开头乘上去的 x^2-1 也就是 (x-1) (x+1) 约去，就有. x^4+x^2+1= (x^2-x+1) (x^2+x+1)\\ 右端这两个二次式在实数范围已经无法分解了，因为它们 判别式 为负。 这样就完成了工作。 2.令 …

The given expression is 4x^2 - 1. We can rewrite this as (2x)^2 - (1)^2. This fits the form a^2 - b^2. Step 2: Identify 'a' and 'b' In this case, a = 2x and b = 1. Step 3: Apply the difference of …
