Решите уравнения:

1) (х – 7)2 + 3 = (х - 2)(х +2)

2) (4х – 3)(3+4х) – 2х(8х – 1) = 0

3) (х +1)(х +2) – (х - 3)(х + 4) = 6

4) (3х -1)( 2х +7) – ( х+1)( 6х – 5) = 7

5) 8m(1+ 2m) – (4m + 3)(4m – 3) = 2m

6) х - 3х(1 – 12х) = 11 – (5 – 6х)(6х + 5)

7) (2х – 3)2 – 2х (4 + 2х) = 11

8) (2х – 3)2 – (7 – 2х)2 = 2

9) (8 – 9а)∙а = - 40 + (6 – 3а)(6 + 3а)

10) 24 –(3у + 1)(4у – 5) = (11 – 6у) (2у-
– 7)

11) (х + 6)2 – (х -5)∙(х + 5) = 79

12) (6х – 1)(6х + 1) – 4х(9х + 2) = -1

13) (6у +2)(5 –у) = 47–(2у -3)(3у – 1)

14) (5х – 1)2 – (1 – 3х)2 = 16х(х – 3)​
