4 b^{2} - 72 = 0

b = 32, b = - 32

Solution steps

4 b^{2} - 72 = 0

Move

72

to the right side

4 b^{2} = 72

Divide both sides by

4

b^{2} = 18

For

x^{2} = f (a)

the solutions are

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

b = 18, b = - 18

18 = 32

- 18 = - 32

b = 32, b = - 32

x^{4} - x^{2} - 42

26 = 6 (5 - a)

x^{3} - 5 x^{2} + 6 x - 30

103 x - 6 = 103 x - 103

1 - p^{3}
