8 - 4 x^{2} = - 172

x = 35, x = - 35

Decimal Notation

x = 6.70820 \dots, x = - 6.70820 \dots

Solution steps

8 - 4 x^{2} = - 172

Move

8

to the right side

- 4 x^{2} = - 180

Divide both sides by

- 4

x^{2} = 45

For

x^{2} = f (a)

the solutions are

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

x = 45, x = - 45

45 = 35

- 45 = - 35

x = 35, x = - 35

x, (x + 4)^{2} = 18

- 3 x^{2} - 9 x - 8 = 0

X^{2} - 2 X - 8 = 0

x, x^{2} + y^{2} = 7 x y

x (3 x + 4) = 2
