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

x = 35, x = - 35

Decimal Notation

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

Solution steps

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

Switch sides

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

Move

2^{2}

to the right side

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

(2 x + 1) (5 x + 2) = (2 x - 2) (x - 2)

16 m^{2} - 25 = 0

(19 x - 2)^{2} - 3 (19 x - 2) - 10 = 0

x^{2} + 2 = 5 (x^{2} + 1)

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