r^{2} + 140 = 0

r = 235 i, r = - 235 i

Solution steps

r^{2} + 140 = 0

Move

140

to the right side

r^{2} = - 140

For

x^{2} = f (a)

the solutions are

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

r = - 140, r = - - 140

- 140 = 235 i

- - 140 = - 235 i

r = 235 i, r = - 235 i

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

2 (10 - x)^{2} = 98

x^{2} - 17 x - 60 = 0

\frac{x + 2}{4} - \frac{x ^{2} - 4}{3} = 2 - \frac{x ^{2} + 2}{6}

\frac{1000}{100} = n^{2} - 54
