(2x+3)2-14x-21=-6

(2 x + 3) 2 - 14 x - 21 = - 6

x = - \frac{9}{10}

Solution steps

(2 x + 3) \cdot 2 - 14 x - 21 = - 6

Move

21

to the right side

(2 x + 3) \cdot 2 - 14 x = 15

Expand

(2 x + 3) \cdot 2 - 14 x : - 10 x + 6

- 10 x + 6 = 15

Move

6

to the right side

- 10 x = 9

Divide both sides by

- 10

x = - \frac{9}{10}

5 - 8 + 3 - 18

x (x + 3) \leq 6 - x^{2} - 3 x

x^{2} - 10 x + 18 = 0

x^{2} = - 6 x

3 ∣ 5 + t ∣ - 1 \geq 26
