-3x + 6 + 15x =11x + 8 ie -3x + 15x - 11x = 8 - 6 ie x = 2
15x + 32x - 28 = 47x - 28 = (√47x)2 - (√28)2 = (√47x)2 - (2√7)2 = (√47x - 2√7)(√47x + 2√7)

Sounds like a system of equations. Y + 5X = - 2 - 15X - 3Y = 6 substitution using first equation Y + 5X = - 2 Y = - 5X - 2 ==========insert into other equation as this is Y - 15X - 3(- 5X - 2) = 6 - 15X + 15X + 6 = 6 ========================This looks to be a dependent system that has an infinite number of solutions
-15x=-5*3x+2 -15x=-15x+2 +15x +15x ----------------- 0=2
-x - 2 + 15x = 14x - 2
18x2 + 15x + 2 = (3x + 2)(6x + 1)
14x6=84+2=86
-x - 2 + 15x = 14x - 2 = 2(7x - 1)
-3x + 6 + 15x =11x + 8 ie -3x + 15x - 11x = 8 - 6 ie x = 2
3x2 + 15x + 6 = 3*(x2 + 5x + 2). There are no further rational factors.
It is: 3x^2 +15x +12
In simple terms: 68-10x
The GCF is 15x.
Yes
It is equivalent to 15x+10
