I please need help in solving a cube surface 6x^2+108x+486
6(x^2 + 18x + 81)
6(x+9)^2
A cube has 6 square faces, so it looks like the side of the cube is x+9.
Don't know what else you're looking for.
steve looking for the length of one side
To solve the equation 6x^2 + 108x + 486, we can use the quadratic formula. The quadratic formula is given by:
x = (-b ± √(b^2 - 4ac))/(2a)
In the equation, a = 6, b = 108, and c = 486. Substituting these values into the quadratic formula, we have:
x = (-(108) ± √((108)^2 - 4(6)(486)))/(2(6))
Simplifying this expression further:
x = (-108 ± √(11664 - 11664)) / 12
x = (-108 ± √0) / 12
Since the discriminant (b^2 - 4ac) is zero, we take the square root of zero, which results in zero. So, we have:
x = (-108 ± 0) / 12
Simplifying even more:
x = -108 / 12
x = -9
Therefore, the solution to the equation 6x^2 + 108x + 486 is x = -9.
