x^{2} + 15 = 6

x = 21, x = - 21

Decimal Notation

x = 4.58257 \dots, x = - 4.58257 \dots

Solution steps

x^{2} + 15 = 6

Square both sides:

x^{2} + 15 = 36

x^{2} + 15 = 36

x = 21

True

, x = - 21

True

The solutions are

x = 21, x = - 21

x, x + p = 10

x^{2} + 3 = 2 x

3 + 3 x - 5 = x

3 + x = 2 + 3 x - 3

2 x = 3
