V(6 - 4х - х^2) - х = 4
V(6 - 4х - х^2) = 4 + x
{V(6 - 4х - х^2)}^2 = {4 + x}^2
6 - 4x - x^2 = 16 + 8x + x^2
2x^2 + 12x + 10 = 0
x^2 + 6x + 5 = 0
x1 = -5
<span>x2 = -1</span>
Решение:
(а-1)(а-4)(а+2)=а^3 - 3а^2 -6а+8а
<span>(4c+2)(3c-5)=12с</span>²<span>- 20
12c</span>²-20c+6c-10=12c²-20
-20c+6c-10=-20
-14c=-20+10
-14c=-10
c=10/14
c=5/7
=============
(4c+2)(3c-5)=12c²-20c+6c-10=12c²-14c-10
