Answer 1

Step-by-step explanation:

Given From the sum of 4x^2 – 3xy + 7x and 5x^2 – 7xy + 5x subtract            4xy – 7x^2

• So we are given the algebraic expressions. So we need to find the sum of two expressions and then subtract the given term.
• So the given expressions are
• 4x^2 – 3xy + 7x + 5x^2 – 7xy + 5x
• So we get 9x^2 – 10xy + 12x  
• So 9x^2 – 10xy + 12x – (4xy – 7x^2)
•     9x^2 – 10xy + 12x – 4xy + 7x^2
•     16x^2 – 14xy + 12x will be the expression
