Ответ:
(y +1)
Step-by-step explanation:
When you multiply the binomials (ay+b)(cy+d), the product is ...
acy² +(ad +bc)y +bd
In this problem, you know the product and you know one of the factors (ay+b) = (5y -7), so ...
ac = 5a = 5bd = -7b = -7These tell you ...
c = ac/a = 5/5 = 1
d = bd/b = -7/7 = 1
Then the other factor is ...
(cy+d) = (y+1)
Check
We can check this by looking at the y-term:
(ad+bc) = -2 . . . . from the given polynomial
(5)(1) +(-7)(1) = 5-7 = -2 . . . . answer checks OK
