Question

Write the polynomial in standard form and also write down their degree.
$(x^2-\frac{2}{3})(x^2+\frac{4}{3})$

Answer 1

$\to (x^2-\frac{2}{3})(x^2+\frac{4}{3})$

$=x^4+(\frac{4}{3}-\frac{2}{3})x^2-\frac{8}{9}$

$=x^4+\frac{2}{3}{x}^2-\frac{8}{9}$

As degree is highest

exponent $\Rightarrow$ Degree $=4$
