3x2 + 48 + 192 = 3x2 + 240 = 3 (x2+ 80)
3x^2+48x+192=3(x^2+16x+62). You can factor the part in the parentheses using the quadratic formula: x= (-b[+-]Sqrt[b^2-4ac])/(2a).
If you notice, 8x + 4 = 4(2x + 1), but there is an odd coefficient for x2, so there is guaranteed to be some remainder (that is 8x + 4 is not a factor of the polynomial): (24x3 - 5x2 - 48x - 8) ÷ (8x + 4) = 3x2 - 2x - 5 - (x2 - 12)/(8x + 4)
8x
The GCF is 24.
3x3 -3x2 - 48x - 60 = 0 simply factor out a 3... 3(x3 - x2 - 16x - 20) = 0
$48x + 5y" is an expression. It is not a function and so cannot be written as a function.
X = 1.5
While it is possible to take 4x out of all of those, it is also possible to add them and get 48x, which factors to 2 * 2 * 2 * 2 * 3 * x
48x2+139+63 = (3x+7)(16x+9) when factored and worked out with the help of the quadratic equation formula
x2 + 48x + 320
x3 + 12x2 + 48x + 64= (x + 4)(x2 + 8x + 16)= (x + 4)(x + 4)(x + 4)= (x + 4)3
