2 r^{2} - 98 = 0

r = 7, r = - 7

Solution steps

2 r^{2} - 98 = 0

Move

98

to the right side

2 r^{2} = 98

Divide both sides by

2

r^{2} = 49

For

x^{2} = f (a)

the solutions are

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

r = 49, r = - 49

49 = 7

- 49 = - 7

r = 7, r = - 7

2 b^{2} - 28 b + 98

x^{3} - 6 x^{2} + 5 x

112 = \frac{8}{2} [2 a + (8 - 1) 3]

70 x^{5} + 100 x

(\frac{6}{z ^{4}})^{3}
