- 4 a^{2} - 37 = - 137

a = 5, a = - 5

Solution steps

- 4 a^{2} - 37 = - 137

Move

37

to the right side

- 4 a^{2} = - 100

Divide both sides by

- 4

a^{2} = 25

For

x^{2} = f (a)

the solutions are

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

a = 25, a = - 25

25 = 5

- 25 = - 5

a = 5, a = - 5

t^{2} + t = - 7

x^{2} - 4 x + 3 = x - 1

r^{2} - 2 r + 17 = 0

x^{2} + 3 x + 5 = 2 x + 7

x^{2} = 7 x
