Answer:
a) (3a-5b)(2x-7) or (-3a+5b)(7-2x)
b) (x-y)(x-y+a) or (y-x)(y-x-a)
Step-by-step explanation:
a) 3a(2x-7)+5b(-(-7+2x))
3a(2x-7)-5b(2x-7)
(3a-5b)(2x-7)
3a(-(-2x+7))+5b(7-2x)
-3a(7-2x)+5b(7-2x)
(-3a+5b)(7-2x)
b)(x-y)^2-a(-(-y+x))
(x-y)^2+a(x-y)
(x-y)(x-y+a)
(-1(-x+y))^2-a(y-x)
(1(y-x)^2-a(y-x)
(y-x)(y-x-a)
The square root of 31 is the only number between 5 and 6
