Question

The sum of coefficients of x4 and x2 of a polynomial 2x5 -3x4+2x3-1

Answer 1

Answer:

-3

Step-by-step explanation:

coefficient of x⁴ is -3

coefficient of x² is 0

their sum is -3

Answer 2

$Polynomial = > 2 {x}^{5} - 3x^{4} + 2{x}^{3} - 1 \\coefficient \: of \: {x}^{4} = - 3 \\ coefficient \: of \: {x}^{2} = 0 \\ now \: sum \: of \: coefficients \: of \: x ^{4} and \: {x}^{2} \\ = - 3 + 0 = - 3$
