factor m^2+2m^2-10m-20

factor

m^{2} + 2 m^{2} - 10 m - 20

3 (m - \frac{5 + 85}{3}) (m - \frac{5 - 85}{3})

Solution steps

m^{2} + 2 m^{2} - 10 m - 20

Add similar elements:

m^{2} + 2 m^{2} = 3 m^{2}

= 3 m^{2} - 10 m - 20

Rewrite as

= 3 (m^{2} - \frac{10 m}{3} - \frac{20}{3})

Factor

m^{2} - \frac{10 m}{3} - \frac{20}{3} : (m - \frac{5 + 85}{3}) (m - \frac{5 - 85}{3})

3 (m - \frac{5 + 85}{3}) (m - \frac{5 - 85}{3})
