How many x intercept appear on the graph of the polynomial function F(x)=x4-5x2
1 answer:
![f(x)=x^4-5x^2\\\\x^4-5x^2=0\\\\x^2(x^2-5)=0\\\\x^2[x^2-(\sqrt5)^2]=0\\\\x^2(x-\sqrt5)(x+\sqrt5)=0\iff x=0\ \vee\ x=\sqrt5\ \vee\ x=-\sqrt5](https://tex.z-dn.net/?f=f%28x%29%3Dx%5E4-5x%5E2%5C%5C%5C%5Cx%5E4-5x%5E2%3D0%5C%5C%5C%5Cx%5E2%28x%5E2-5%29%3D0%5C%5C%5C%5Cx%5E2%5Bx%5E2-%28%5Csqrt5%29%5E2%5D%3D0%5C%5C%5C%5Cx%5E2%28x-%5Csqrt5%29%28x%2B%5Csqrt5%29%3D0%5Ciff%20x%3D0%5C%20%5Cvee%5C%20x%3D%5Csqrt5%5C%20%5Cvee%5C%20x%3D-%5Csqrt5)
