There are four solutions to 9x4 plus 27x3 - 4x2 - 12x equals 0. One of the solutions is x = -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)
4x2-4x-120 = (2x+10)(2x-12) when factored
4x2 + x2 = 8 + x2
True
4x2+12x = 4x(x+3) when factored
4x2 + 12x + 5 = (2x + 1)(2x + 5).
x2-3x+2.25 is the same as 4x2-12x+9 and is (2x-3)(2x-3) when factored
Operational signs would make this a lot easier. Assuming that's + 12x + 5, the answer is (2x + 1)(2x + 5)
4x2 = -12x, divide both sides by 4x: x = -3
Only if the value of c is 9 because:- 4x2+12x+9 = (2x+3)(2x+3)
There are four solutions to 9x4 plus 27x3 - 4x2 - 12x equals 0. One of the solutions is x = -3.
12x * 4x2 = 48x3
It can be factored as: 4x(x+228)
4x2 + 12x + 5 = 4x2 + 2x + 10x + 5 = 2x(2x+1) + 5(2x+1) = (2x+1)(2x+5)
4x2+49x+90 = (4x+9)(x+10) when factored
4x2 is 8+ 12x + 3 collect like terms, 8+3= 11, 12x+11 to solve for x, transpose the 11 to the other side of the = sign, 12x=-11, divide by 12, x=-11/12
