Answer:
∴(x+5)(x+3) =x²+8x+15
Explanation:
Standard form of a polynomial:
Standard of polynomial means that the terms ordered from biggest exponent of variable to lowest exponent of variable.
Example:
![a_nx^n+a_(n-1)x^(n-1)+a_(n-2)x^(n-2)+......](https://img.qammunity.org/2021/formulas/mathematics/high-school/2dpdr0z2yavvt5kz3yt4883263p15s71ub.png)
Given,
(x+5)(x+3)
=x(x+3)+5(x+3)
=x²+3x+5x+15
=x²+8x+15
∴(x+5)(x+3) =x²+8x+15
The degree of the polynomial is 2 and is a one variable polynomial.
