3x^2-5=x(3x+1)

Solution

3 x^{2} - 5 = x (3 x + 1)

Solution

x = - 5

Solution steps

3 x^{2} - 5 = x (3 x + 1)

Expand

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

3 x^{2} - 5 = 3 x^{2} + x

Move

5

to the right side

3 x^{2} = 3 x^{2} + x + 5

Subtract

3 x^{2} + x

from both sides

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

Simplify

- x = 5

Divide both sides by

- 1

x = - 5
