x^{2} + 8 = 15

x = 7, x = - 7

Decimal Notation

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

Solution steps

x^{2} + 8 = 15

Move

8

to the right side

x^{2} = 7

For

x^{2} = f (a)

the solutions are

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

x = 7, x = - 7

1 + 2 + 3 + n = \frac{1}{2} n (n + 1)

4 x^{2} + 20 x + 45 = 0

(x - 4)^{2} + 5 x (x - 1) = 16

1 5^{2} = 2 0^{2} + x^{2} - 2 \cdot 20 \cdot x \cdot 0.75

2 u^{2} + u - 1 = 0
