x^{3} + 2 x^{2} - 49 x - 98 = 0

x = - 2, x = - 7, x = 7

Solution steps

x^{3} + 2 x^{2} - 49 x - 98 = 0

Factor

x^{3} + 2 x^{2} - 49 x - 98 : (x + 2) (x + 7) (x - 7)

(x + 2) (x + 7) (x - 7) = 0

Using the Zero Factor Principle:

ab = 0

then

a = 0

b = 0

x + 2 = 0 or x + 7 = 0 or x - 7 = 0

Solve

x + 2 = 0 : x = - 2

Solve

x + 7 = 0 : x = - 7

Solve

x - 7 = 0 : x = 7

The solutions are

x = - 2, x = - 7, x = 7

(7.2 + x^{2})^{2} = x^{2} + 2.6 7^{2}

6 x^{4} = 1296 x

2 x^{3} - 9 x^{2} + 12 x - 4 = 0

r^{4} - 16 = 0

x^{8} + 8 x^{4} + 18 = 0
