All real values of x
Step-by-step explanation:
3 (12x²+x+1) + 12 (12x²+x+1) = 15 (12x²+x+1)
(12x² + x + 1) (3+12) = 15 (12x²+x+1)
15 (12x²+x+1) = 15 (12x²+x+1)
Since both sides are identical, all real values of x will satisfy the equation

infinite solutions
Step-by-step explanation:
3 (12x2+x+1) + 12 (12x2+x+1) = 15 (12x2+x+1)
Combine like terms
3 (12x2+x+1) + 12 (12x2+x+1) = 15 (12x2+x+1)
15 (12x2+x+1) = 15 (12x2+x+1)
Divide by 15
(12x2+x+1) = (12x2+x+1)
Since they are the same
x can be any real value
