Question

The degree of given polynomial
${ - 4x}^{3} + {2x}^{2} - 5x + {4x}^{3} { - 1}^{7}$
Is _____
​

Answer 1

$\huge\boxed{\fcolorbox{white}{blue}{Degree- Highest power}}$

So,

$\: the \: degree \: of \: - 4 {x}^{3} + 2 {x}^{2} - 5x + 4 {x}^{3} - {1}^{7}$ will be 7

In the whole polynomial 7 is the only highest power among all

So 7 is the ansswer
