Question

(x²+5)(3-x³) degree of the polynomial.​

Answer 1

3

step by step explanation:

(x^2+5) (3-x^3)

$= ( {x}^{2} + 5)( - {x}^{3} + 3) \\ = ( {x}^{3} + 3) \times {x}^{2} + 5( - {x}^{3} + 3) \\ = - {x}^{3} \times {x}^{2} + 3 {x}^{2} + 5( - {x}^{3} + 3) \\ = - {x}^{3} \times {x}^{2} + 3 {x}^{2} - 5 {x}^{3} + 15 \\ = - 5 {x}^{3} - {x}^{3} \times {x}^{2} + 3 {x}^{2} + 15$
