Some signs would have made life easier at this end.
(3x + 9)(x + 9) is a possibility, as is (3x - 9)(x - 9)
81.
(3x - 30)(x + 8) can also simplify to 3(x - 10)(x + 8)
3x2-27 is equal to -21.
If you mean: 9x2-36x+16 then it is not a perfect square because its discriminant is greater than zero
The factors of 81 are numbers that can be multiplied together to give 81. The factors of 81 are 1, 3, 9, 27, and 81. Prime factors are the factors that are prime numbers. The prime factors of 81 are 3 and 3, or written as 3^4.
3x2 + 36x + 81 = 3(x2 + 13x + 27)
3x2 + 36x + 81 = 3(x2 + 12x + 27) = 3(x + 3)(x + 9), which are its prime factors; or, if you prefer, 3x2 + 36x + 81 = (3x + 9)(x + 9), which is also accurate. You may easily verify these results by multiplying back.
(3X + 9) (X + 9)
90720^2=8230118400
4x2-36x+81 (2x-9)(2x-9)
4x2 - 36x + 81 = 4x2 - 18x - 18x +81 = 2x(2x - 9) - 9(2x - 9) = (2x - 9)2
The expression is likely 4x2 - 36x +81 which is the same as (2x - 9)(2x - 9) or (2x - 9)2
-3x2+10x-3 -(3x2-10x+3) -(3x-1)(x-3)
3x2 + 10x + 3 = (x + 3)(3x + 1).
The prime power factorization of 81 is 34.
find the prime factorization to the number 81
If that's + 81, the answer is (2x - 9)(2x - 9) or (2x - 9)2 If that's - 81, it gets ugly in a hurry.
