I think you mean (3x ± 1)^2 = (3x+1)(3x-1)?
If this is algebra then; 3x plus 12x = 15x
-3x + 10x = 7x3x + 3x = 6x
4x + 5 = 3x + 84x-3x + 5 - 5 = 3x - 3x + 8 -5x = 3
plot 4y then 3x
In the equation 3x plus 7 equals 13, x is equal to 2.
8x + 7
No. 3x plus 2x = 5x. 3x multiplied by 2x = 6x²
2x + 20 = 3x20 = 3X - 2X20 = X
3x plus -5 equal 7. so x is 4 so 3times 4 is 12-5 will equal 7.
10x+4y+11xy
-8x
