ANSWER:-
6x^2+3=-11x
By arrenging properly we get
6x^2+11x+3=0
then by middle term splitting
6x^2+2x+9x+3=0
2x(3x+1)+3(3x+1)
(2x+3)(3x+1)
their factor
x=-3/2 Or X=-1/3
HOPE U ARE SATISFIED

Answer:
→ 6x^2 + 3 = - 11x
→ 6x^2 + 3 + 11x = 0
→ 6x^2 + 11x + 3 = 0
Splitting 11 in two parts such that product of those parts becomes equal to the product of 6 and 3.
→ 6x^2 + ( 9 + 2 )x + 3 = 0
→ 6x^2 + 9x + 2x + 3 = 0
→ 3x( 2x + 3 ) + ( 2x + 3 ) = 0
→ ( 2x + 3 ) ( 3x + 1 ) = 0
→ 2x + 3 = 0 or 3x + 1 = 0
→ 2x = - 3 or 3x = - 1
→ x = - 3/2 or x = - 1/3
