What is the resolve form of 9x2 - 9x - 4 in factor?
3x + 1)(3x - 4)
How do you factor 3x2-9x-912?
3x2 - 9x - 912 = 3(x2 - 3x - 304) = 3(x - 19)(x + 16).
How do you factor 6Xcubed plus 10Xsquared minus 9X minus 20?
(3x - 4)(2x^2 + 6x + 5)
Factor this 9x2 plus 27?
9x(x2+3x-10) * * * * * 9x3 + 27x2 - 90x = 9x(x2 + 3x - 10) = 9x(x + 5)(x - 2).
What is the expression of 9x to the secound power minus 30x plus 25?
That can be factored to (3x - 5)(3x - 5) or (3x - 5)2
How do you factor 3x2-9x?
factor out a 3x 3x(x-3)=3x2-9x
What is the greatest common factor of 6x and 9x?
The GCF of 6x and 9x is 3x
What is the factor of 9x squared -16?
(3x-4)(3x+4)
How do you factor the given polynomial 9x2 plus 9x-10?
9x2 + 9x - 10 =(3x - 2)(3x + 5)
How do you factor 9x squared minus 49?
It is a difference of squares. 9x^2-49=(3x+7)(3x-7)
What is the factor of 3x plus 21x plus 9x?
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.
What is 3x2 plus 9x divided by 3x?
3X^2 + 9X/3X factor out 3X 3X(X + 3)/3X 3X/3X = 1, so... X + 3 is the simplest form here
How do you factor 3x2 9x3?
To factor the expression 3x^2 - 9x^3, we first need to find the greatest common factor (GCF) of the two terms. The GCF of 3x^2 and 9x^3 is 3x^2. We can factor out 3x^2 from both terms to get 3x^2(1 - 3x). Therefore, the factored form of 3x^2 - 9x^3 is 3x^2(1 - 3x).
How do you factor 9x squared minus 64?
(3x + 8)(3x - 8)
How do you factor 12x2-9x?
3x(4x - 3)
Factor 9x cubed plus 27x squared -90x?
Step 1: Divide by 9x: 9x (x2 + 3x - 10) = 9x(x + 5)(x - 2)
What is the resolve form of 9x2 - 9x - 4 in factor?
3x + 1)(3x - 4)
