Let's simplify the left side of the equation:
8(3+2x) - (4x+3)(4x-3)= 8(3) + 8(2x) - (16x^2 - 12x + 12x - 9)= 24 + 16x - 16x^2 + 12x - 12x + 9= -16x^2 + 8
The simplified equation is not equal to 9x - 6.
Let's simplify the left side of the equation:
8(3+2x) - (4x+3)(4x-3)
= 8(3) + 8(2x) - (16x^2 - 12x + 12x - 9)
= 24 + 16x - 16x^2 + 12x - 12x + 9
= -16x^2 + 8
The simplified equation is not equal to 9x - 6.
