9^{2} + 2^{2} = x^{2}

x = 85, x = - 85

Decimal Notation

x = 9.21954 \dots, x = - 9.21954 \dots

Solution steps

9^{2} + 2^{2} = x^{2}

Switch sides

x^{2} = 9^{2} + 2^{2}

Simplify

9^{2} + 2^{2} : 85

For

x^{2} = f (a)

the solutions are

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

x = 85, x = - 85

(x + 4) (x + 6) = 0

21 = - x^{2} + 10 x

2 x^{2} - 16 x + 24

2 x^{2} - 3 x - 14 = 0

(x + 3)^{2} + 20 = 0
