Question

What is the answer to this?

Answer 1

$\\ \sf\longmapsto (19xy+3y-28)-(-15xy-2y-15)$

• Remove brackets

$\\ \sf\longmapsto 19xy+3y-28+15xy+2y+15$

• Combine like variables

$\\ \sf\longmapsto 19xy+15xy+3y+2y-28+15$

$\\ \sf\longmapsto 34xy+5y-13$

Answer 2

The subtraction of the polynomial (19xy + 3y - 28) - (- 15xy - 2y - 15) is 34xy + 5y - 13

How to subtract polynomial

Given:

(19xy + 3y - 28) - (- 15xy - 2y - 15)

• Open the parenthesis

= 19xy + 3y - 28 + 15xy + 2y + 15

• collect like terms

= 19xy + 15xy + 3y + 2y - 28 + 15

= 34xy + 5y - 13
