I think you mean (3x ± 1)^2 = (3x+1)(3x-1)?
3x+42=6x+12 42=6x-3x+12 42=3x+12 42-12=3x 30=3x 10=x
If you mean 3x+4y = 12 then y = -3/4x +4
you mean: x+3x+3=x+18 so x=5
Let the symbol ^ mean "to the power" Then 9x^2 + 24x + 16 = (3x + 4)(3x +4) = (3x + 4)^2
I think you mean (3x ± 1)^2 = (3x+1)(3x-1)?
Presumably you mean: 9x2+24x+16? (3x+4)(3x+4)
3x+42=6x+12 42=6x-3x+12 42=3x+12 42-12=3x 30=3x 10=x
If you mean: 3x^2 +31x +36 then it is (3x+4)(x+9) when factored
If you mean 3x+4y = 12 then y = -3/4x +4
you mean: x+3x+3=x+18 so x=5
If you mean: 3x+2 = 8 then x = 2
If you mean: 2x-3 = 3x+3 then x = -6
No. It is 9x, which is a monomial.
Let the symbol ^ mean "to the power" Then 9x^2 + 24x + 16 = (3x + 4)(3x +4) = (3x + 4)^2
If you mean 3x + 2x = 100, then x = 20. If you mean something different, you'll need to spell it out.
3x + 2 = 3x + 6 This is not possible.
