The property used to rewrite 9x2 + 9x3 is the Distributive Property. Using the Distributive Property the expression can be rewritten as 9x2 + 9x2 + 9x2 or 27x2.

(3x)^(2-4) = (3x)^-2 = (9x2)^-1 = 1/(9x2)

9x2 + 7x = 2 9x2 + 7x - 2 = 0 9x2 + 9x - 2x - 2 = 0 9x(x + 1) - 2(x + 1) = 0 (9x - 2)(x + 1) = 0 x ∈ {-1, 2/9}

Factor: 9x2 - 25.

This type of statement is called a difference of squares. If you see an equation in the form:a2 - b2then it is also equal to:(a + b)(a - b)In this case 9x2, and 25 are both perfect squares. 9x2 is equal to (3x)2 and 25 is equal to 52, so the that statement can be factored out as:(3x - 5)(3x + 5)

The property used to rewrite 9x2 + 9x3 is the Distributive Property. Using the Distributive Property the expression can be rewritten as 9x2 + 9x2 + 9x2 or 27x2.

(3x2 + 2x + 1)

If the question could more exactly be phrased as, "What is the value of x when 9x2 - 16 = 0", the answer is, x = 4 or -4. This answer can be found by factoring 9x2 - 16 into (3x + 4)(3x - 4) and setting each factor equal to zero.

If you mean: 9x2+3x-2 = (3x+2)(3x-1) when factored

(3x)^(2-4) = (3x)^-2 = (9x2)^-1 = 1/(9x2)
