r^{2} + 49 = 0

r = 7 i, r = - 7 i

Solution steps

r^{2} + 49 = 0

Move

49

to the right side

r^{2} = - 49

For

x^{2} = f (a)

the solutions are

x = f (a), - f (a)

r = - 49, r = - - 49

- 49 = 7 i

- - 49 = - 7 i

r = 7 i, r = - 7 i

36 - x^{2}

- 3 x^{3} - 3 x^{2} + 168 x

(\frac{20}{3})^{2}

9 (3 x + 6) = 14 - (x + 2)

4 x^{2} + 8 x - 8
