Question

Find the
degree of Polynomial (y³-7) (y⁷-8)​

Answer 1

Answer:

degree is 7 because y⁷ is the greatest term in the question

Answer 2

Answer:

$(y^3-7) (y^7-8)$

    Using formula, $\left(a+b\right)\left(c+d\right)=ac+ad+bc+bd$

                              $a=y^3,\:b=-7,\:c=y^7,\:d=-8$

$y^3y^7+y^3\left(-8\right)+\left(-7\right)y^7+\left(-7\right)\left(-8\right)$

$y^{10}-7y^7-8y^3+56$

Degree -  The largest exponent/power the variable has in a polynomial with one variable.

We can see the largest exponent/power in the polynomial $y^{10}-7y^7-8y^3+56$ is 10
