Question

xsquare +1 has ni real zeroes. why?​

Answer 1

Step-by-step explanation:

For example, z2+1 has no real zeros (because its two zeros are not real numbers). x2−2 has no rational zeros (its two zeros are irrational numbers). ... The fundamental theorem of algebra states that a polynomial (with real or complex coefficients) of degree n has n zeros in the complex numbers (counting multiplicities).
