Beetle · Answer 1

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
