factor 12x^3-21x^2-45x

factor

12 x^{3} - 21 x^{2} - 45 x

3 x (4 x + 5) (x - 3)

Solution steps

12 x^{3} - 21 x^{2} - 45 x

Factor out common term

3 x : 3 x (4 x^{2} - 7 x - 15)

= 3 x (4 x^{2} - 7 x - 15)

Factor

4 x^{2} - 7 x - 15 : (4 x + 5) (x - 3)

= 3 x (4 x + 5) (x - 3)

5 (\frac{1}{5})^{- 2} - 5 (\frac{2 ^{2}}{3})

72 (\frac{π}{180})

2 [3 x - (4 x - 6)] = 5 (x - 6)

7^{- 2}

75 x^{2} + 35 x - 10 = 0
