r^{2} + 2 r^{2} = 10

r = \frac{10}{3}, r = - \frac{10}{3}

Decimal Notation

r = 1.82574 \dots, r = - 1.82574 \dots

Solution steps

r^{2} + 2 r^{2} = 10

Add similar elements:

r^{2} + 2 r^{2} = 3 r^{2}

3 r^{2} = 10

Divide both sides by

3

r^{2} = \frac{10}{3}

For

x^{2} = f (a)

the solutions are

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

r = \frac{10}{3}, r = - \frac{10}{3}

x^{2} - 9 = 35

(3 z - 15)^{2} + 43 = - 2

2 x^{2} - 20 x + 46 = 0

8^{2} + x^{2} = 1 1^{2}

3 x^{2} - 26 x + 16 = 0
