x2+8x+4
Delta = 82-4x1x4 = 48 = 4 x sqrt(3)
so x2+8x+4= (x-((-8-sqrt(48))/2) (x-((-8+sqrt(48))/2) = (x+4+2 sqrt(3)) (x + 4 -2 sqrt(3))

What binomial is a factor of this trinomial x2 plus 8x plus 16?
x + 4
Factor x2 plus 8x?
x2 + 8x = x(x+8)
What is the answer to 24x3-5x2-48x-8 divided by 8x plus 4?
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)

Factor the polynomial x2 - 8x plus 16?
(x-4)(x-4)
Factor x2 plus 8x?
x2 + 8x = x(x+8)
Factor 2x3 4x2 - 8x?
If that's + 4x2, the answer is 2x(x2 + 2x - 4)

Does this have a factor x2-8x plus 6?
That does not factor neatly.
Factor x2 - 8x plus 16 Enter each factor as a polynomial in descending order?
(x - 4)(x - 4)
Factor x2 plus 8x plus 15?
x2 + 8x + 15 = (x + 3)(x + 5)
Which of the following factor of x2-8x plus 15?
x2-8x+15 = (x-3)(x-5)
How do you factor x2 plus 8x plus 15?
x2 + 8x + 15 = (x + 3) (x + 5).
X2 -8x equals 1?
x2 - 8x = 1 ∴ x2 - 8x + 16 = 17 ∴ (x - 4)2 = 17 ∴ x - 4 = ±√17 ∴ x = 4 ± √17
