Find the Roots (Zeros) h(x)=5x^4+7x^8-x^12

$h (x) = 5 x^{4} + 7 x^{8} - x^{12}$

Step 1

Set $5 x^{4} + 7 x^{8} - x^{12}$ equal to $0$ .

$5 x^{4} + 7 x^{8} - x^{12} = 0$

Step 2

Graph each side of the equation. The solution is the x-value of the point of intersection.

$x \approx - 1.66326846, 0, 1.66326846$
