Question

Multiply x^2+5•x^3+7
I’m getting x^5+5x^3+7x^2+35 But I’m not sure if I’m right

Answer 1

x⁵ + 5x³ + 7x² + 35

Explanation:

(x² + 5) (x³ + 7)

To distribute binomials (expressions with two terms), you can use the FOIL method (First, Outer, Inner, Last):

x⁵ + 7x² + 5x³ + 35

To put into standard form, rearrange from highest power to lowest power:

x⁵ + 5x³ + 7x² + 35
