sqrt(81x2)=9x*sqrt=square root of
3x+21x+9x=33x. Break it apart. The factor of x is x and the factors of 33 are 3 and 11. Therefore, the factors of 3x+21x+9x are 3, 11, and x.
9x + 1x = 10x.
x+5+3x-7+9x+3-4x Collect like terms: 9x+1
81x2 + 72x + 16 = 81x2 + 36x + 36x + 16 = 9x(9x + 4) + 4(9x + 4) = (9x + 4)2
82
If you mean (9x-8y)(9x+8y) then it is 81x^2 minus 64y^2
102 +9x +4 = 9x + 106, which is in its simplest form.
