Need equivalent expression for 4x squared minus 12x plus 9?
4x2 - 12x + 9 = 4x2 - 6x - 6x + 9 = 2x(2x - 3) - 3(2x - 3) = (2x - 3)(2x - 3) or (2x - 3)2
6x - 8 plus 2x - 5 equals 7 - 2x?
6x - 8 + 2x - 5 = 7 - 2x ?
How would you factor 24x3 plus 72x2 plus 30x?
24x^3 + 72x2 + 30x = 6x*(4x^2 + 12x + 5)=6x*(2x + 1)*(2x + 5)
Solve for X 6x-8 plus 2x-5 equals 7-2x?
6x-8+2x-5 = 7-2x 6x+2x+2x = 7+8+5 10x = 20 x = 20/10 x = 2
X plus 2x plus 6x?
x + 2x + 6x = 9x
2x plus 6x plus 4x 12?
2x + 6x + 4x = 12x
What is 10 plus 6x plus 6x equals -14?

What is 6x to the fifth power plus 12x divided by negative 2x to the negative 3 power?
(6x^5 + 12x) / (-2x^-3) =[ (6x^5 + 12x) (x^3) ] / (-2) =(6x^8 + 12x^4) / (-2)=(3x^8 + 6x^4) =(3x^4)[ (x^4) + 2 ]
5x plus x - 6x plus 2x equals 9?
5x + x - 6x + 2x = 2x
What is the quotient and remainder when 12x4 -7x2 plus 1 is divided by 2x plus 1?
Fill in the missing powers of x in the dividend by having a coefficient of zero (0); then use long division: _________________ 6x³ - 3x² - 2x + 1 ________--------------------------------- 2x + 1 | 12x⁴ + 0x³ - 7x² + 0x + 1 _________ 12x⁴ + 6x³ _________ ------------- _______________ - 6x³ - 7x² _______________ - 6x³ - 3x² _______________ ------------- ____________________ - 4x² + 0x ____________________ - 4x² - 2x ____________________ ------------ ____________________________ 2x + 1 ____________________________ 2x + 1 ____________________________ -------- __________________________________0 ____________________________ ===== → (12x⁴ - 7x² + 1) ÷ (2x + 1) = 6x³ - 3x² - 2x + 1 with no remainder.
