9 x^{2} - 1 = 0

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

Decimal Notation

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

Solution steps

9 x^{2} - 1 = 0

Factor

9 x^{2} - 1 : (3 x + 1) (3 x - 1)

(3 x + 1) (3 x - 1) = 0

Using the Zero Factor Principle:

ab = 0

then

a = 0

b = 0

3 x + 1 = 0 or 3 x - 1 = 0

Solve

3 x + 1 = 0 : x = - \frac{1}{3}

Solve

3 x - 1 = 0 : x = \frac{1}{3}

The solutions to the quadratic equation are:

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

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

(x - 7)^{2} + 3 (x + 8) = 2

8 x^{2} - 4 x - 4 = 0

r, 2 π r^{2} + 2 π r h = A

(x) = x^{2} - x
