x ³+ x ²- X + 1, which is already the simplest form in the range of real numbers, may be the formula X ³+ x ²- An error occurred in one of the symbols in X + 1, such as X ³- x ²- x+1=x ² (x-1)-(x-1)=(x-1)(x ²- 1)=(x-1) ² (x + 1), and so on

The fourth power of x minus 15 times the square of x plus 10x plus 24 equals 0

x^4-15x^2+10x+24=0x^4-15x^2+44+10x-20=0(x ²- 11)(x ²- 4)+10(x-2)=0(x+2)(x-2)(x ²- 11)+10(x-2)=0(x-2)(x ³+ 2x ²- 11x-12)=0(x-2)[x(x+1) ²- 12(x+1)]=0(x-2)(x+1)(x ²+ x-12）=0(x-2)(x+...

What is the square of X to the power of N + 1? And this question: the n-th power of X × The N + 1 power of X × The 2n power of (- x) × 2n + 3rd power of X + (- x) × 2n-2 power of X × x=________________ (process required, If it is 2n + 1 power of the square of (- x)=____

(x^2)^n+1)=x^[2 × (n + 1) = x ^ (2n + 2) x to the nth power × The N + 1 power of X × The 2n power of (- x) × 2n + 3rd power of X + (- x) × 2n-2 power of X × X = n-th power of X × The N + 1 power of X × 2n power of X × 2n + 3rd power of x-x × 2n-2 power of X × x=x^(n+n+1+2n+1)-x^(2n+3+2n-2+1)=x^...

What is the y = SiNx / TaNx image?

y=sinx/(sinx/cosx)=cosx,x∈{x|x≠kπ/2,k∈Z}
That is, y = cosx image removes the center of symmetry and points on the axis of symmetry. For example, the images corresponding to x = 0, π / 2, π,... Are hollow

What is the number of intersections between the images of the functions y = SiNx and y = TaNx on the interval [0,2 π]? I count three, but how do I count five?

You're right
Only three
It's all their zeros

In the interval (- 1.5pi, 1.5pi), the number of image intersections of the functions y = TaNx and y = SiNx is?

Draw an image, it can be seen that there are five
