factor 3x^2+x^2-21x+14

factor

3 x^{2} + x^{2} - 21 x + 14

4 (x - \frac{21 + 217}{8}) (x - \frac{21 - 217}{8})

Solution steps

3 x^{2} + x^{2} - 21 x + 14

Add similar elements:

3 x^{2} + x^{2} = 4 x^{2}

= 4 x^{2} - 21 x + 14

Rewrite as

= 4 (x^{2} - \frac{21 x}{4} + \frac{7}{2})

Factor

x^{2} - \frac{21 x}{4} + \frac{7}{2} : (x - \frac{21 + 217}{8}) (x - \frac{21 - 217}{8})

4 (x - \frac{21 + 217}{8}) (x - \frac{21 - 217}{8})

f (3 x^{8})
