Question

P(x)=x^4-5x^2+4
Its zeros are X1= ___, X2=___,X3=___,X4=__, with X1<_ X2<_ X3<_ X4

Answer 1

The zeros or roots of the equation p(x) = x⁴ - 5x² + 4 are

X₁ = -2

x₂ = -1

x₃ = 1

x₄ = 2

What are zeros of polynomial equation

The zeros of a polynomial equation are the values of the variable that make the polynomial equal to zero.

On a graph, this is the point where the graph intercepts the x-axis.

Hence we find the x-values where the polynomial intercept the x-axis as

A (-2, 0)

B (-1, 0)

C (1, 0)

D (2, 0)
