rational roots

x^{3} + 2 x^{2} - 19 x - 20

x = - 1, x = 4, x = - 5

Solution steps

x^{3} + 2 x^{2} - 19 x - 20

Validate the roots by plugging them into

x^{3} + 2 x^{2} - 19 x - 20 = 0 : x = - 1, x = 4, x = - 5

x = - 1, x = 4, x = - 5

4 x^{3} + 2 x - 4 = 0

5 x^{4} - 25 x^{2} - 10 = 0

4 r - 3 = 3 (3 r^{4})

3 x^{3} + 4 x^{2} + 4 x + 9 = 9

x^{5} = 5 x^{3}
