-0.2x2+12x+11 = 0
Using the quadratic equation formula will give you two solutions which are:
x = 30 + the square root of 955 = 60.90307428 to 8 decimal places.
or:
x = 30 - the square root of 955 = -0.90307428 to 8 decimal places.
There are four solutions to 9x4 plus 27x3 - 4x2 - 12x equals 0. One of the solutions is x = -3.
2*2 - 12x +16 =0 4 - 12x +16 =0 -12x + 16 +4 =0 -12x + 20 =0 -12x = -20 x = 1.666666667

10+12x=-14 -14-10=12x 12x=-24 x=-2
It is: 12x
It is an equation.
30+12x = 6(5+2x)
12x = x + 3 11x = 3 x = 3/11
x=5
6x + 12x + 2x = 80 20x = 80 x = 4
9x + 2 = 12x + 14 -3x = 12 x = -4
12x - 8 = 10x + 42x = 12x = 6
There are four solutions to 9x4 plus 27x3 - 4x2 - 12x equals 0. One of the solutions is x = -3.
