2 (3 x + 5)^{2} - 2 = 70

x = \frac{1}{3}, x = - \frac{11}{3}

Decimal Notation

x = 0.33333 \dots, x = - 3.66666 \dots

Solution steps

2 (3 x + 5)^{2} - 2 = 70

Move

2

to the right side

2 (3 x + 5)^{2} = 72

Divide both sides by

2

(3 x + 5)^{2} = 36

For

(g (x))^{2} = f (a)

the solutions are

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

Solve

3 x + 5 = 36 : x = \frac{1}{3}

Solve

3 x + 5 = - 36 : x = - \frac{11}{3}

The solutions to the quadratic equation are:

x = \frac{1}{3}, x = - \frac{11}{3}

5 x^{2} - 15 x + 1 = 0

21 x^{2} - 16 x - 50 = 0

64 b^{2} + 48 b + 9 = 0

x^{2} + x + 11 = 5 x - 8

2 v^{2} + 4 v + 12 = 0
