Question

(2x^2y+14xy)-(-8x^2y-9xy+5)

Answer 1

2x2y+14xy−(−8x2y−9xy+5)

Explanation:

Evaluation for x=1,y=1

2(1(2)(1))+(14)(1)(1)−(−8(1(2)(1))−(9)(1)(1)+5)

2(1(2)(1))+(14)(1)(1)−(−8(1(2)(1))−(9)(1)(1)+5)

=28

This is the best I can do when given the example of x = 1 and y = 1

Hope this helps you!!

Answer 2

the answer is 10x^2y + 23xy - 5
