x2 + 12x + 27 = (x + 9)(x + 3)
8x^3 - 12x^2 + 6x - 9 = (8x^3 - 12x^2) + (6x - 9) = 4x^2(2x - 3) + 3(2x - 3) = (4x^2 + 3)(2x - 3)
You need to rivse your question. It appears that there is not an equation here. 4*2+12x+9? You can't really solve this it is more of a statement. You can however simplify it to 12x+17- Whoever wrote this obviously can't read. It's supposed to be 4x^2+12x+9 (2x+3)(2x+3)
3x multiplied by (12x plus 9) is:3x(12x + 9)= (3x * 12x) + (3x * 9)= 36x2 + 27x
The value of X in the equation 3x 2-12x plus 9 is 1.25.
x2 + 12x + 27 = (x + 9)(x + 3)
No solution. Multiply second equation by 3 and get 12x + 6y = 0 but already stated 12x + 6y = 9...
(2x - 3)(2x - 3)
8x^3 - 12x^2 + 6x - 9 = (8x^3 - 12x^2) + (6x - 9) = 4x^2(2x - 3) + 3(2x - 3) = (4x^2 + 3)(2x - 3)
4x² - 12x + 9 = 5 → 4x² - 12x + 4 = 0 → x² - 3x + 1 = 0 → x = (-(-3) ±√((-3)² - 4×1×1))/(2×1) → x = (3 ±√5)/2 → x = (3 + √5)/2 or x = (3 - √5)/2

y = - 4x - 4
8x2 + 6x - 9 = 8x2 + 12x - 6x - 9 = 4x(2x + 3) - 3(2x + 3) = (2x + 3)(4x - 3)
12X - 7 = 4X + 9 subtract 4X from both sides 8X - 7 = 9 add 7 to both sides 8X = 16 divide both sides by 8 X = 2 check 12(2) - 7 = 4(2) + 9 24 - 7 = 8 + 9 17 = 17 checks
3x multiplied by (12x plus 9) is:3x(12x + 9)= (3x * 12x) + (3x * 9)= 36x2 + 27x
If you mean: 4x squared+12x+9 then it is (2x+3)(2x+3)
If you mean 12x+3y = -9 and -8x-2y = 14 then they are y = -4x-3 and y = -4x-7 respectively which means that they are parallel lines because they both have the same slope of -4 but with different y intercepts
