因式分解 3(a)^2-(a)+5

解答

因式分解

3 (a)^{2} - (a) + 5

3 a^{2} - a + 5

求解步骤

3 a^{2} - (a) + 5

Check the discriminant:

- 59

Since the discriminant is negative, the polynomial has no real roots and thus cannot be factored further

= 3 a^{2} - a + 5

f a c t or 1 - x^{2}

f a c t or x^{2} + 2 - 1

f a c t or a^{6} b^{6} - 0.01

f a c t or x^{3} y^{6} z^{12} - 512
