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.

2x + 5 + 3x = 25 5x + 5 = 25 Subtract 5 from both sides: 5x = 20 Divide both sides by 5: x = 4

6x

3x plus 9 equals what?

3x + 5 = -20. First, subtract 5 from both sides of the equation: 3x + 5 - 5 = -20 - 5; and simplify: 3x = -25. Then divide both sides by 3: 3x / 3 = -25 / 3; and simplify: x = -8 1/3 (or -8.33)

-2x^4+16 +2x^4+9-3x^5=-3x^5+25. There is no "answer" because there is no equation.

x = 3

-3x + (-18) = 2x + 7 +18 +18 -3x = 2x +25 -2x -2x -5x = 25 ----- ----- -5 -5 x=-5 *------- equals a division line

That can be factored to (3x - 5)(3x - 5) or (3x - 5)2

If: 8x-4 = 3x+21 Then: 8x-3x = 21+4 => 5x = 25 => x = 25/5 Therefore: x = 5

(x^2 - 3x + 5)(x^2 + 3x + 5)

25-7=18 18/3=6

No. It is 9x, which is a monomial.
