x^{2} + 9 = 16

x = 7, x = - 7

Decimal Notation

x = 2.64575 \dots, x = - 2.64575 \dots

Solution steps

x^{2} + 9 = 16

Move

9

to the right side

x^{2} = 7

For

x^{2} = f (a)

the solutions are

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

x = 7, x = - 7

8 a^{2} = 17 a

x^{2} - 9 x + \frac{81}{4} = 0

a^{2} - 16 = 32

(3 x + 2)^{2} = 49

2 y (8 y + 3) = 1
