3a^2-4=(6a(2a-3))/4

3 a^{2} - 4 = \frac{6 a ( 2 a - 3 )}{4}

a = \frac{8}{9}

Decimal Notation

a = 0.88888 \dots

Solution steps

3 a^{2} - 4 = \frac{6 a ( 2 a - 3 )}{4}

Multiply both sides by

4

12 a^{2} - 16 = 6 a (2 a - 3)

Expand

6 a (2 a - 3) : 12 a^{2} - 18 a

12 a^{2} - 16 = 12 a^{2} - 18 a

Move

16

to the right side

12 a^{2} = 12 a^{2} - 18 a + 16

Subtract

12 a^{2} - 18 a

from both sides

12 a^{2} - (12 a^{2} - 18 a) = 12 a^{2} - 18 a + 16 - (12 a^{2} - 18 a)

Simplify

18 a = 16

Divide both sides by

18

a = \frac{8}{9}

x - \frac{1}{5} = 31

x, 3 x + 5 y = 6 x + 24

x, f (x - 1) = 6

n \cdot p_{6} = \frac{1}{2}

x, f + f (\frac{1}{x}) = 0
