Kneel down to seek the great God of mathematics to solve the problem (X & # 178; + 5x + 3) (X & # 178; + 5x-2) - 6

Kneel down to seek the great God of mathematics to solve the problem (X & # 178; + 5x + 3) (X & # 178; + 5x-2) - 6

Take X & # 178; + 5x as a whole
(X²+5X+3)(X²+5X-2)-6=(X²+5X)²+(X²+5X)-12=(X²+5X+4)(X²+5X-3)=(x+1)(x+4)(X²+5X-3)
X & # 178; + 5x-3 can only be decomposed by the root formula

On the equation of X (A & # 178; - 1) x = 2 (a + 1), when a = 1, the equation ()
A has no solution
B has only one solution
C has innumerable solutions
D has only integer solutions

a=1,
The equation is as follows:
0× x=2×2
That is: 0 = 4
Obviously X has no solution
Option a
