It’s 25 dummy next time be smart
A) the greatest common factor is y^2 so
y^2(3x^2-x-2)
...
B) x^2+6x+9
x^2+3x+3x+9
x(x+3)+3(x+3)
(x+3)(x+3)
(x+3)^2
C)
x^2-25
x^2-5x+5x-25
x(x-5)+5(x-5)
(x+5)(x-5)
Answer:
a:b = 5:4 = 35:28 (multiplying by 7)
b:c = 7:3 = 28:12 (multiplying by 4)
now a:b:c = 35:28:12
hope it helped
