9x^2 +6 +1 is (3x+1)(3x+1) when factored
(3x + y)(3x - y)
9x2
(9x2 + 7)(9x2 - 7) = 81x4 - 49
9x2 + 25 has no rational factors. Its factorisation in the complex domain is:(3x + 5i)*(3x - 5i) where i is the imaginary square root of -1.
For example: 9x2-25 = (3x-5)(3x+5) but this only applies to negative expressions it wouldn't apply to 9x2+25
(3x2 + 2x + 1)
Answer this question…A. x4 + 2x3 + 9x2 + 4 B. x4 + 4x3 + 9x2 + 4 C. x4 + 2x3 + 9x2 + 4x + 4 D. x4 + 2x3 + 9x2 - 4x + 4
-5y2+3x+2y
This is an expression, not an equation. Expressions cannot be solved.
9x2+9x-12 All I can do is simplify this. I can't solve it unless turn this expression into an equation.
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.
TrUE
k = -3; factors are (9x + 3)(x - 1)
48
3x2(x2 - 3)
= 53 9x3 + 9x2 + 5x1+ 3x1 27 + 18 + 5 + 3
One of the factors is 3x + 8b. The other is 9x^2 -24xb + 64b^2
