(2x+3)2-4(2x+3)-12=0

(2 x + 3) 2 - 4 (2 x + 3) - 12 = 0

x = - \frac{9}{2}

Solution steps

(2 x + 3) \cdot 2 - 4 (2 x + 3) - 12 = 0

Add similar elements:

2 (2 x + 3) - 4 (2 x + 3) = - 2 (2 x + 3)

- 2 (2 x + 3) - 12 = 0

Move

12

to the right side

- 2 (2 x + 3) = 12

Divide both sides by

- 2

2 x + 3 = - 6

Move

3

to the right side

2 x = - 9

Divide both sides by

2

x = - \frac{9}{2}

12 x - 42 = 18

x, y - 2 = 1 x - 1

x, 5 x + y = 4

p, y^{2} = 2 p x

0 = 2
