Question

which of the following quadratic polynomial x+4,x^3+x,x^3+2x+6,x^2+5x+4
​

Answer 1

Answer:

Only x²+5x+4 is a quadratic equation.

Answer 2

ANSWER✔

$\large\underline\bold{GIVEN,}$

$\sf\dashrightarrow x+4,x^3+x,x^3+2x+6,x^2+5x+4$

$\large\underline\bold{TO\:FIND,}$

$\sf\dashrightarrow WHICH\:ONE\:IS\: QUADRATIC\: POLYNOMIAL$

$\large\underline\bold{SOLUTION,}$

$\red{\text{NOTE:-QUADRATIC POLYNOMIAL MEANS,A POLYNOMIAL OF TWO DEGREES }}$

$\sf\dashrightarrow x+4=linear \: polynomial$

$\sf\dashrightarrow x^3+x= cubic \:polynomial$

$\sf\dashrightarrow x^2+5x+4= quadratic\:polynomail$

$\large\underline\bold{x^2+5x+4\:IS\:A\: QUADRATIC\:POLYNOMIAL.}$
