Answer:
1) 6a+8b+7ab
2) -2x2+3y2-2y+11
Step-by-step explanation:
1) sum of two numbers = 5ab + 3b+7a
rearrange the following = 7a + 3b + 5ab
one number = -2ab + a - 5b
rearrange the following = a-5b-2ab
other number = (7a +3b +5ab)-(a-5b-2ab)
= 7a+3b+5ab - a +5b + 2ab
= 6a+8b+7ab
2) obtained number= x2-2y+6
one number = 3y2-4x-3x2-5
rearrange the following= 3x2-3y2-4x-5
other number= (x2-2y+6)-(3x2-3y2-4x-5)
= x2-2y+6-3x2 + 3y2 +4x +5
= -2x2+3y2-2y+11
